Alkyl, aryl and hetaryl acetylenes - highly reactive multifunctional compounds (a review)

Abstract

The author’s data (2000-2022) on synthesis methods, reactivity and applied aspects of aryl- and hetarylacetylenes were summarized. The specificity of alkynylarenes (hetarenes) associated with the activation of the triple bond by acceptor groups were noted. Particular attention was paid to fundamentally important new reactions of heterocyclization and complete soft cleavage of the triple bond. The prospects for the use of alkynylarenes and -hetarenes and their modification products were reflected. The results of screening of the synthesized compounds were presented.
