Abstract

Methods for carrying out coupling reactions in the chemistry of alkynes to form C–C bonds (oxidative dehydrocondensation reactions, Cadiot–Chodkiewicz reaction, and Sonogashira reaction) are analyzed and generalized. Protocols of synthesis of products of these reactions are also presented, including homogeneous and heterogeneous catalytic systems. In all cases, emphasis is placed on the kinetics and mechanisms of reactions with the discussion of the results of kinetic and spectrometric studies of the mechanisms of coupling reactions involving Cu(I, II, III), Au(I, III), Pd(0, I, II), and Fe (0, I, II, III) complexes. Particular attention is paid to the heterogeneous catalysis of oxidation reactions of alkynes with the participation of nanoparticles and nanoclusters of Pd, Au, Ag, and other metals. The nature of the intermediates containing these metals and the relationships between various oxidative and nonoxidative transformations of alkynes are discussed.

炔烃均相催化化学的“黄金时代”：炔烃的一些氧化转化（综述）

摘要

对炔烃化学中进行偶联反应形成 C-C 键的方法（氧化脱氢缩合反应、Cadiot-Chodkiewicz 反应和 Sonogashira 反应）进行了分析和概括。还提出了这些反应产物的合成方案，包括均相和非均相催化系统。在所有情况下，重点都放在反应动力学和机理上，讨论涉及 Cu(I, II, III)、Au(I, III)、Pd( 0、I、II) 和 Fe (0、I、II、III) 配合物。特别关注钯、金、银和其他金属纳米粒子和纳米团簇参与下炔烃氧化反应的多相催化。
