Gold as a catalyst. Part II. Alkynes in the reactions of carbon - carbon bond formation

This publication continues the series of reviews devoted to the current state of gold catalysis in organic chemistry. The second review addresses Au-catalyzed reactions of alkynes, giving rise to carbon -carbon bonds. Most of the described reactions are addition reactions involving the triple bond of alkynes. The review covers both intramolecular reactions, including cyclization of various substrates (enynes, diynes, enediynes, etc.) and enyne isomerization without ring formation, and intermolecular reactions, including alkyne reactions with alkenes, other alkynes, heteroaromatic compounds, etc., in particular, tandem reactions. A special part is devoted to dual gold catalysis involving the intermediate formation of binuclear complexes with a- and it-coordinated metal atoms. The last part of the review deals with the carbon -carbon bond formation reactions in which the alkyne triple bond is retained.
