Boron-containing compounds (BCCs) have emerged as a new class of organic molecules in pharmaceutical chemistry as novel drug candidates for extensive therapeutic applications. In this context, the five novel bioactive spiroborate compounds (S₁-S₅) were synthesized by condensation reaction of Schiff base ligands (L₁-L₅), 1,3-dioxane-5,5-dimethanol, and boric acid with high yields. The bioactive spiroborate compounds (S₁-S₅) were characterized by NMR (¹H and ¹¹B) spectra, FT-IR spectra, UV–Vis spectra, LC-MS/MS spectrometry, elemental analysis, and melting point measurement techniques. The anti-cancer activity in A549 lung cancer cells and inhibitory effects of α-glucosidase with acetylcholinesterase (AChE) enzymes of the synthesized spiroborate compounds were investigated. In addition, the anti-bacterial activity of spiroborate compounds against Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Escherichia coli were investigated, respectively. On the other hand, anti-biofilm activity against Pseudomonas aeruginosa was assessed. In silico studies were also conducted on the synthesized spiroborate molecules (S₁-S₅). Among the synthesized spiroborate compounds, spiroborate (B₅) was identified as the most potent anticancer agent with an IC₅₀ of 352.5 µg/ml, in contrast spiroborate (B₃) exhibited the strongest α-glucosidase inhibition (68 %) and anti-bacterial activity. Furthermore, spiroborate (B₄) was the most effective AChE inhibitor (61 %). Besides, spiroborate (B₄) exhibited strong antibacterial activity against S. aureus and E. coli with MIC values of 7.81 μg/mL. Spiroborate compounds (S₁-S₅) exhibited significant dose-dependent biofilm inhibitory activity against P. aeruginosa. The binding affinities of spiroborate (B₄) to the proteins 3VSL and 4WUB were calculated as −4.16 and −4.26 kcal/mol.

Nowadays, a considerable amount of research is focused on cyclodextrin chemistry because it is economically and environmentally helpful; also, they are eco-friendly biomimetic materials, water-soluble, low-price, commercially available, easily functionalized, and non-toxic. These particular properties make cyclodextrin (CD) an appealing and invaluable field for study. β-CD can make host-guest complexes by non-covalent bonding, leading to highly selectively catalyzed chemical reactions. Indeed, β-CD has been vastly applied as a green nanocatalyst for organic conversions. In this regard, Cu(II)-β-CD is a dinuclear complex with great stability constants that recently received massive attention in organic chemistry. Cu(II)-β-CD is easily accessible and structurally simple and can be a promising catalyst in different organic conversions. This review concentrates on using copper(II)-β-CD catalyst as an advantageous catalyst in the diverse organic reactions and summary articles.

Green synthesis is a method of chemical synthesis that aims to reduce the environmental impact of chemical reactions and techniques. Green synthesis techniques use plant extracts, microorganisms, or proteins as bio-capping and bio-decreasing agents and their role as bio-nanofactories for prepare biogenic nanoparticles (NPs). Green chemistry emphasizes the minimization of hazardous compounds, reduction of waste generated in conventional organic synthesis, and consideration of both production and disposal impacts. Since 2011, the adoption of green chemistry techniques has led to a 27 % reduction in chemical waste, with enhanced chemical recycling playing a significant role. Key reduction strategies include process modifications, elimination of toxic reagents, and reduction in the number of steps required in organic synthesis. Moreover, green chemistry-based sustainable synthesis and nanomaterial surface fabrication have attracted attention due to their superior catalytic properties, ease of handling, reusability, cost-effectiveness, and biocompatibility. For instance, metal NPs synthesized from plant extracts and animal waste have gained popularity as bio-reductants for various organic transformations. The pharmaceutical industry is increasingly committed to sustainable chemistry practices to produce modern medicines and improve the greenness of numerous drugs. This review will primarily examine the steps, concepts, and techniques fundamental to green chemistry.

Computational studies were performed to provide mechanistic insights into the (4+1) carbocyclization mechanism from chalcones with internal alkynes catalyzed by rhodium catalysis. Computational results suggested that cationic rhodium (C_p^tRhOAc⁺) was generally used as the active catalyst, and the generation of 2H-furanium salt can be divided into three stages: formation of pyrylium salt, hydrolysis, and 2H-furanium salt formation. The factors responsible for the regio-, chem- and stereo-selectivities are discussed. The regio- and chem-selectivity step is identified as the migratory insertion process in the first catalytic cycle. The reason can be understood from the electronic effect. The stereochemistry-determining-step is the migratory insertion process in the second catalytic cycle, which can be ascribed to the steric effect as RSS-TS_21–22 identifies a more expansive structure.

Carbon quantum dots and metal-doped carbon quantum dots (N-CQDs and M-CQDs) were prepared by the hydrothermal method. The samples were characterized by EDS, UV–Vis, FT-IR, XRD, and PL techniques. FT-IR investigation demonstrates that M-CQDs have a shift of the peak associated with C-O and C=O oxygen bonds due to doping metals into carbon quantum dots, and a band at 550 cm^-1, which is related to M-O bonds. N-CQDs and M-CQDs exhibited impressive PL behavior as an antibacterial factor against representative Gram-negative and Gram-positive bacterial strains. According to the findings and comparisons of the average halo zone of the anti-bactericidal activity of the prepared samples and MIC methods, N-CQDs and M-CQDs demonstrate excellent prevention versus bacteria with the best MIC of 0.5 mg/L. Co-CQDs had the greatest inhibitory effect against S. aureus with an average halo zone diameter of 15 mm, and E. coli with an average halo zone diameter of 13 mm. This toxicity is due to the generation of reactive oxygen species and the interaction between the M-CQDs and cells.

Diruthenium bis(μ-ethylidyne) complex [(Cp*Ru)₂(μ-CMe)₂] (1) reacts smoothly with metal carbonyls of group 6–9 3d metals to afford heterobimetallic tri- and tetranuclear complexes. While bis(ethylidyne) complexes [(Cp*Ru)₂(μ-CMe)(μ₃-CMe)(μ-CO)₂{Cr(CO)₃}] (2) and [(Cp*Ru)₂(μ₃-CMe)₂(μ-CO){Fe(CO)₃}] (4) were obtained by the reaction of 1 with [Cr(CO)₆] and [Fe(CO)₅], respectively, the reaction with [Mn₂(CO)₁₀] yielded μ-vinylidene−μ₃-ethylidyne complex [(Cp*Ru)₂(μ-C=CH₂)(μ₃-CMe)(μ-CO)₂{Mn(CO)₃}] (3) accompanied by the abstraction of a methyl proton by [Mn(CO)₅]^•. By the reaction with an excess amount of [Co₂(CO)₈], tetranuclear bis(μ₃-ethylidyne) complex [(Cp*Ru)₂(μ₃-CMe)₂(μ-CO){Co(CO)₂}₂] (6) was exclusively obtained. These reactions implied that the delocalized π-electrons in the [Ru₂C₂] core of 1 were used to construct the heterometallic skeleton with unsaturated organometallic species. Although complexes 2 and 3 underwent fragmentation upon gentle heating, 4 reacted with CO at 60 °C to yield μ₃-η²(||)-butyne complex [(Cp*Ru)₂(μ₃-η²(||)-MeCCMe)(μ₃-CO)(μ-CO){Fe(CO)₃}] (5) via the alkylidyne−alkylidyne coupling. The density functional theory (DFT) calculations suggested that the C−C bond formation occurs via the intermediate containing μ- and μ₃-ethylidyne ligands followed by the migration of the m-ethylidyne ligand across the Ru₂Fe plane.

The cycloaddition reaction of CO₂ to synthesize cyclic carbonates is highly valuable for greenhouse gas resource utilization. In this study, a multifunctional g-C₃N₄@MOFs layered catalyst (BCN-MIL-IMNH₂), containing Lewis acid-base sites and hydrogen bond donors (HBD), was prepared using a mild in-situ growth and covalent bonding strategy. At optimal performance conditions (120 °C, 1.5 MPa, 90 mg catalyst, 4 h), the BCN-MIL-IMNH₂–2 catalyst exhibited excellent catalytic performance (Y_PC = 96.5 %, S_PC = 99.0 %). The remarkable catalytic efficiency resulted from the combined effect of Lewis acid (B/Cr), Lewis base (Br⁻), and hydrogen bond donors (-NH₂) active groups. The introduced Cr and B were effective in activating and opening (via nucleophilic attack by Br⁻) epoxides. Besides, the -NH₂ group, serving as a hydrogen bond donor basic functional group, adsorbed and activated CO₂ to form an intermediate carbamate. The enhanced stability was attributed to the covalent bonding strategy, which effectively immobilizes the amino functionalized ionic liquids within the MOFs of the composite material, thereby enhancing structural stability and preventing dissociation during the reaction process. After five cycles, the catalyst maintained excellent performance with a yield of approximately 93 %.

Development of carbon-rich organometallic systems containing rigid, π-conjugated fragments is a hot research topic. Construction of donor-acceptor skeleton with the thiophene donor group and the acceptor units such as benzothiazole and fluorenone can usually improve the electronic properties of the resulting organic materials. New nanoscale-sized organometallic acetylide polymers of platinum(II) bridged by bis(thienyleneethynylene)-benzothiadiazole moiety P1 and bis(thienyleneethynylene)-fluorenone moiety P2 have been synthesized in which an additional triple bond was inserted between the thiophene ring and the acceptor unit in the central spacer unit. The photophysical and electrochemical properties of P1 and P2 were investigated and compared with those of their model diplatinum(II) complexes and related polymers with other heteroaromatic spacers.

Three novel ferrocene-based organometallic complexes of zinc, containing either homoleptic or heteroleptic (mixed-ligand) structures [Zn (FcBz)₂ (H₂O)₂] (1), [Zn (FcBz)₂ Bipy] (2), [Zn (FcBz)₂ Phen] (3), which FcBz = 4-ferrocenyl benzoate, Phen = 1, 10-phenanthroline, Bipy = 2, 2-bipyridyl, were chemically synthesized and well characterized by ¹³C NMR, ¹H NMR, FT-IR, elemental analysis and thermal gravimetric analysis (TGA). The synthesized complexes incorporate ligands that exhibit bidentate chelation, resulting in hexacoordinate geometry. The complexes were exposed to antibacterial testing against pathogenic Gram-negative and Gram-positive bacteria. Antimicrobial research revealed that heteroleptic complexes outperformed homoleptic ones. The [Zn (FcBz)₂Phen] complex exhibited the highest efficacy, making it a viable organometallic contender for antibacterial applications.
