“Golden Age” of Homogeneous Catalytic Chemistry of Alkynes: Oxidative Тransformations of Alkynes. Review

Abstract

The methods of carrying out the coupling reactions in the alkynes chemistry were analyzed and generolyzed. Formation of C–C bonds in the reactions of oxidative dehydrocondensation, Kadio–Chodkevich and Sonogashira were considered. The protocols of these reactions were presented. The accent was made on the results of kinetic and spectrometric investigations of coupling reaction mechanisms with participation of Cu(I, II, III), Au(I, III), Pd(O, I, II), and Fe(O, I, II, III) complexes. The special attention was payed to heterogeneous catalysis of oxidative reactions of alkynes with participation of nanoparticles and nanoclusters of Pd, Au, Ag and other metals. The nature of intermediates with the complexes of Cu, Au, Pd and Fe and mutuality of different oxidative and nonoxidative transformations of alkynes were discussed.
