In recent years, special emphasis has been put on spirocyclization reactions of biaryl ynones since these strategies offer versatile platforms for introducing various important functional groups into spirocyclic frameworks in a step‐economical manner, which is conducive to drug discovery. In this regard, various functionalized spiro[5.5]trienones and 3,3‐spiroindanones have been synthesized via the radical, radical cation, or electrophilic process promoted by thermal, photochemical, and electrochemical means. In this invited review, we systematically summarize the spirocyclization reactions of biaryl ynones with diverse organic precursors, highlighting the reaction patterns, mechanistic insights, and synthetic applications.

Metal‐covalent organic frameworks (M‐COFs) are a class of crystalline porous materials formed by the coordination bonds between metals centers and covalent organic frameworks (COFs). They retain the characteristics of COFs while providing exposed metal active sites. Compared with homogeneous transition metal catalysts, M‐COFs exhibit superior catalytic activity, high stability, tunability, high specific surface area, and ordered pore channels. More importantly, due to their heterogeneous nature, M‐COFs catalysts can be reused multiple times conveniently, avoiding the residual presence of transition metals and reducing resource and environmental consumption. This review introduces the general design strategies and synthesis methods of M‐COFs, briefly discusses the intrinsic relationship between their structure and catalytic activity, and focuses on summarizing their applications in organic transformations. It also highlights the advantages and challenges of M‐COFs in catalyzing organic transformation reactions and discusses the future development directions in this field.

A novel photochemical trifluoromethylation/cyclization of unactivated alkenes to synthesize trifluoromethyl‐substituted quinazolinones with trifluoromethylsulfonyl‐pyridinium salt (TFSP) is achieved under catalyst‐free conditions. Mechanistic studies reveal that an electron‐donating‐accepting complex is formed between the quinazolinone and TFSP, making this the first example of TFSP‐based trifluoromethylation conducted in the absence of expensive iridium photocatalysts.

A series of chiral potassium Brønsted bases containing 3,3′‐substituted 1,1′‐bi‐2‐naphthol‐based chiral crown ethers are demonstrated as sustainable metal catalysts for a tandem allylic isomerization/asymmetric aldol–Tishchenko reaction. The crown ether creates an effective chiral environment around the potassium cation, yielding diverse 1,3‐diols containing three contiguous stereogenic centers with excellent diastereoselectivity and high enantioselectivity. This system allows the use of allylic alcohols instead of enolizable ketones as nucleophiles, thus broadening the synthetic applicability of this reaction.

A sustainable and efficient electrochemical method for the direct oxidative lactonization of benzylic alcohols, enabling rapid access to isobenzofuran‐1(3H)‐ones (phthalides) is presented. This electrocatalytic transformation leverages N‐hydroxyphthalimide as a redox mediator under mild, metal‐free conditions, offering an environmentally friendly alternative to traditional oxidation protocols. The method demonstrates broad substrate scope and delivers phthalide derivatives consistently in good to excellent yields. Mechanistic studies, combining cyclic voltammetry and density functional theory calculations, support a radical‐mediated hydrogen atom transfer mechanism driven by phthalimide‐N‐oxyl radicals. Importantly, the utility of the protocol extends beyond model substrates: it is successfully applied to the synthesis of pharmaceutically relevant compounds, including talopram and a key intermediate for a neuropeptide Y5 receptor antagonist. Overall, this work underscores the power of electrosynthesis in modern organic chemistry, merging green chemistry principles with synthetic efficiency.

Methylation reactions have extraordinary value in organic chemistry, ranging from the assembly of structurally diverse organic functional chemicals to the introduction of methyl groups into pharmaceutical and agrochemical intermediates. In the context of sustainable chemistry, carbon dioxide (CO2) has emerged as an idea and alternative greener C1 source. As a result, reductive methylation strategies utilizing CO2 as a methylating agent have garnered substantial research interest in recent decades, particularly for synthesizing methylated derivatives, compounds with broad applications in drug discovery and agrochemical development. In this review, reductive methylations using CO2 as C1 synthon have been summarized and discussed in detail with focus on metal‐catalyzed C/N‐methylation reactions, base catalyzed C/N‐methylation reactions, ionic liquids catalyzed C/N‐methylation reactions, and catalyst‐free C/N‐methylation reactions based on various reductants. We also elucidate substrate compatibility in these reductive methylations, competing side reactions, and representative reaction mechanisms. Furthermore, conclusions and future trends are depicted finally in this review.

Organosilicon compounds (OSCs), which consist of silicon atoms bonded to organic groups, have become vital in fields such as materials science, catalysis, and electronics. Their flexibility comes from the ability to adjust their properties by attaching different organic groups to the silicon framework. Despite many progresses, a key challenge persists in controlling the structure and reactivity of these compounds, particularly on a solid surface. Scanning probe microscopy (SPM) techniques, including scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), and atomic force microscopy (AFM), are powerful tools for studying molecular behaviors at the atomic level. These techniques enable real space imaging and precise measurements, making them invaluable for understanding OSCs. This article examines the application of STM, STS, and AFM in the on‐surface chemistry of organosilicon, with a focus on molecular adsorption, self‐assembly, surface‐driven reactions, and innovative synthesis of nanostructures. These techniques can provide valuable insights into surface reactivity, molecular organization, and the formation of nanostructures, driving the development of advanced functional materials. Further, density functional theory offers exciting opportunities for advancing surface chemistry and nanomaterial design. This article highlights the critical role of SPM in pushing forward OSCs research and enabling the development of next‐generation organosilicon nanomaterials.

Amide bonds are ubiquitous in bioactive molecules, yet their synthesis often relies on prefunctionalized reagents or stoichiometric activators, posing sustainability challenges. Herein, we report a novel electrochemical decarboxylative amidation strategy enabling direct coupling of α‐keto acids with arylamines to access N‐arylamides under mild, oxidant‐free conditions. This redox mediator‐controlled indirect electrolysis harnesses ferrocene to facilitate single‐electron oxidation of α‐keto acids, generating acyl radicals that couple with anodically oxidized arylamine radicals to form amides efficiently. This programmable approach offers operational simplicity and synthetic versatility, providing streamlined access to valuable amide scaffolds with promising applications in medicinal chemistry.
