Abstract

A metal-free esterification of a broad range of alkynes with alcohols in the presence of phenyliodine bis(trifluoroacetate) produces esters in good yields via carbon triple bond cleavage. The transformation proceeds via hydroxyethanones and ethanediones as intermediates and exhibits a broad substrate scope and good functional group tolerance.
