Volume 3 covers carbon-to-carbon single bond forming reactions involving sp3, sp2 and sp carbon centers, but only those which do not involve additions to C-X &pgr;-bonds. The volume first compares and contrasts the alkylation reactions of all types of sp3 carbon nucleophiles and also covers vinyl and alkynyl carbanions. Following on from Volume 2, a separate section covers Friedel-Crafts alkylation reactions, which is complemented by discussions of polyene cyclizations and electrophilic transannular cyclizations in synthesis. Coupling reactions leading to &agr;-bond formation, and involving all types of combinations ofsp3, sp2 and sp carbon centers are next covered, including those reactions based on pinacol, acyloin and phenol oxidative coupling reactions, and also the Kolbe reaction. Rearrangement reactions, leading to carbon-to-carbon &agr;-bond formation, are often used in a clever manner in synthesis. The volume includes all those rearrangement reactions based on intermediate carbonium ions and carbanions, and also includes the benzil-benzilic acid and the Wolff rearrangements. The volume closes with coverage of carbonylation reactions, and the use of carbene insertion reactions into the C-H bond in synthesis.

The construction of C-X (X = C, N, S) bonds is an important research content in the field of organic synthesis and drug preparation. Focusing on the green construction of the core skeleton of functional fine chemicals, the team has carried out research on green synthesis and catalytic reactions of fine chemicals, realized the effective synthesis of high value-added fine chemicals, and obtained a series of new systems of transition metal palladium and copper-catalyzed halogenated aromatic hydrocarbons involved in C-C and C-N coupling reactions; realized the efficient preparation of biphenyl, arylamine and aryl thioether compounds using water as solvent. Aiming at atomic economy, we realized the new method of direct C-H functionalization of arenes to construct C-C and C-S bond formation, as well as the construction of structurally complex functional molecular skeletons through one-pot multi-step reactions, laying a solid foundation for the application of fine organic synthesis technology in the fields of pharmaceutical intermediates, agrochemicals and optoelectronic materials, forming a distinctive research direction of fine chemical synthesis technology and it has formed a distinctive research direction of fine chemical synthesis technology and a stable R&D team, and improved the technical level of preparation of high value-added fine chemicals. He has published a total of 30 academic papers, including 27 SCI papers.
