Abstract In this work, we have developed a simple one-step synthesis of Ni2P and CoP phosphides based on a carbonization process. The current approach uses glucose as a reductant instead of H2 and employs inert gas as feed gas. The Ni2P/C and CoP/C obtained by the glucose route showed higher CH4-CO2 reforming performance than corresponding phosphides prepared by traditional H2 reduction method, which should be attributed to the fact that the phosphides prepared by glucose route had higher surface areas and smaller particle sizes than the ones prepared by traditional method.

Abstract We report a rapid, efficient, economic, environmentally benign, and easy to scale-up method for the synthesis of phosphonamide derivatives using ultrasound irradiation, under catalyst and solvent-free conditions starting from the corresponding amine and phenyl phosphonic dichloride. The reaction was achieved in excellent isolated yield in a short reaction time at room temperature. The structures of the synthesized compounds are confirmed by elemental analysis as well as by IR and 1H, 13C, 31P NMR spectroscopic data and mass spectrometry. Graphical Abstract

Abstract Pyridoxonium salts of chiral linear and cyclic dithiophosphoric acids were obtained by the reactions of pyridoxine with bis{2-О-[2-methyl-(2S)-3-O-propionyl]}, bis{2-О-[1,4-О,О-dimethyl-(2S)-succinyl]}, and O,O-di-2-butyl dithiophosphoric acids, and cyclic dithiophosphoric acids of 1,3,2-dioxaphosphorinane, 1,3,2-dioxaphospholane, and 1,3,2-dioxaphosphepin structure. Syntheses of acetonide pyridoxonium О,О-dimenthyl dithiophosphates were carried out by the reaction of seven-membered pyridoxine acetonide with О,О-dimenthyl dithiophosphoric acids obtained from (–)-(1 R,2S,5R)-menthol and (+)-(1S,2R,5S)-menthol. Diacetonide pyridoxonium bisdithiophosphonate was also prepared. The antibacterial and antifungal activities of pyridoxonium chiral linear and cyclic dithiophosphates were evaluated.

Abstract 2-(1-((3-Substitutedureido/thioureido)methyl)cyclohexyl)acetic acid derivatives (1–9) were synthesized from gabapentin. All the synthesized compounds were characterized by using IR, 1H-NMR, 13C-NMR spectroscopy, mass spectrometry and elemental analysis. Urea and thiourea derivatives were investigated for their potential in vitro anticancer activities on PC3 and MCF7 cancer cell lines using MTT assay. Cell apoptosis was detected by with Annexin V Assay. Our results showed that compound 8 {2-(1-((3-(2,6-dichlorophenyl)ureido)methyl)cyclohexyl)acetic acid} significantly inhibited the proliferation and growing of PC3 and MCF7 cells. Both cell types showed dysfunction of cellular morphology which induced apoptosis 10 µM concentration of compound 8 treated cells. Our results indicate that compound 8 might have significance as an anti-tumor agent against human prostate and breast cancer. The theoretical structure and activity estimation via in silico ADMET was also examined. Graphical Abstract

Abstract The review discusses recent achievements in the development of more ecofriendly and economically viable processes for the synthesis of biologically potent α-aminophosphonates via Kabachnik-Fields reaction by three-component coupling of carbonyl, amine and hydrophosphoryl compounds. These α-aminophosphonates exhibited promising antioxidant, antimicrobial and anticancer activity. Some recent developments on the synthesis of biologically active α-aminophosphonates in the presence of various catalysts, in catalytic solvent medium, in catalyst-free solvent medium, under solvent-free conditions, and reactions in solution are discussed. Miscellaneous reactions are also included. Graphical Abstract

Abstract A one-pot and oxidative method is described for the first time for the conversion of benzylic trimethylsilyl (TMS) and tetrahydropyranyl (THP) ethers to gem-dichlorides using trichloroisocyanuric acid (TCCA) and triphenylphosphine (PPh3) in neutral media. Various theses substrates containing electron withdrawing or donating groups can be efficiently converted to their corresponding gem-dichlorides in good to excellent yields. The present method shows a high degree of chemoselectivity, and due to its one-pot nature is in accordance with green chemistry. Graphical Abstract

Abstract We have synthesized a series of phosphoramidates containing a heterocyclic moiety with good yields (88–95%) by the reaction of (E)-5-benzylidene-3-((2-hydroxyethoxy)methyl)thiazolidine-2,4-dione with ethyl phosphorodichloridate followed by the reaction with various heterocyclic amines. The designed compounds were primarily screened for their ability to inhibit pancreatic α-amylase enzyme using in silico molecular docking approach. The compounds with good binding energies (−8.0 to −6.9 kcal/mol) when compared with standard drug, acarbose (−8.0 kcal/mol) were prompted for the synthesis. The structures of the newly prepared compounds were confirmed by their spectroscopic analyses. They were further screened in vitro for their inhibition toward α-amylase enzyme using acarbose as standard drug. All compounds exhibited moderate to good inhibition potential with IC50 values in the range of 54.14 ± 0.35 to 185.04 ± 0.53 µg/mL when compared with the standard drug (IC50, 50.47 ± 0.28 µg/mL). Especially, the compound (E)-2-((5-benzylidene-2,4-dioxothiazolidin-3-yl)methoxy)ethyl ethyl 1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-ylphosphoramidate (6f) (IC50, 54.14 ± 0.35 µg/mL) and (E)-2-((5-benzylidene-2,4-dioxothiazolidin-3-yl)methoxy)ethyl ethyl benzo[d]thiazol-2-ylphosphoramidate (6c) (IC50, 57.02 ± 0.32 µg/mL) exhibited the best inhibition among the synthesized compounds.

Abstract The [4 + 2] cycloaddition reaction (McCormack reaction) of 1,3-butadiene with dichloromethylphosphine (DCMP) yielding 3-phospholene oxide has been studied by density functional theory (DFT) at the M06-2x/6-311++G(2d,2p) computational level. This reaction is a cheletropic process that comprises two steps with the formation an ionic intermediate in the first step and subsequently, its hydrolysis, in the second step. For the first step of this reaction, three paths were considered as a stepwise pathway with a diradical intermediate and an assumed path with a trigonal intermediate that compared with the concerted path in terms of energy. Analysis of the reactivity indices showed that the 1,3-butadiene and DCMP behaved as nucleophile and electrophile, respectively. Graphical abstract

Abstract In this review, the structural data of monomeric platinum(II) complexes with inner coordination spheres of Pt(η2-P2L)(SiL)2, Pt(η2-P2L)(η2-Si2L) and Pt(η2-P,SiL)2 are classified and analyzed. These complexes crystallize in three crystal systems: monoclinic (8 examples), triclinic (4 examples) and orthorhombic (4 examples). Distorted square-planar environments about the Pt(II) atoms are built up by combination of homobi-P,P with two monodentate Si donor ligands; homobi-PP with homo-Si,Si donor ligands, or heterobi-P,Si donor ligands. The chelating ligands create metallacycles with the following angles: 65.0° (SiOSi) < 83.1° (SiC2Si) < 85.2° (PC2P) < 88.8° (SiSi2Si)). The mean Pt-P and Pt-Si bond distances in Pt(η2-P2L)·(SiL)2 complexes are 2.319 and 2.365 Å; in Pt(η2-P2L)(η2-Si2L) the values are 2.316 and 2.360 Å. The complex [Pt{η2-Me2P(C2B10H10)SiMe2}2] exists in two isomeric forms, a monoclinic cis- and a triclinic trans-isomer. The structural data are compared and discussed with the complexes of inner coordination spheres: Pt(η2-P2L)(XL)2 (X = O, N, CN, BL, Cl, SL, SeL, Br, or I) and Pt(η2-P2L)(η2-X2L) (X = OL, NL, SL or SeL).

The chelating ligands create metallacycles with the following angles: 65.0° (SiOSi) < 83.1° (SiC2Si) < 85.2° (PC2P) < 88.8° (SiSi2Si)). The mean Pt-P and Pt-Si bond distances in Pt(η2-P2L)·(SiL)2 complexes are 2.319 and 2.365 Å; in Pt(η2-P2L)(η2-Si2L) the values are 2.316 and 2.360 Å. The complex [Pt{η2-Me2P(C2B10H10)SiMe2}2] exists in two isomeric forms, a monoclinic cis- and a triclinic trans-isomer. The structural data are compared and discussed with the complexes of inner coordination spheres: Pt(η2-P2L)(XL)2 (X = O, N, CN, BL, Cl, SL, SeL, Br, or I) and Pt(η2-P2L)(η2-X2L) (X = OL, NL, SL or SeL).
