Palladium(0)-Catalyzed Decarboxylation of Buta-2,3-dienyl 2‘-Alkynoates: Approach to the Synthesis of 2-Alkynyl Buta-1,3-dienes

Abstract

The Pd(PPh3)4-catalyzed decarboxylation of buta-2,3-dienyl 2'-alkynoates allows the rapid construction of 2-alkynyl buta-1,3-dienes. The carbon-carbon bond-forming reaction occurs at the central position of an allene moiety.
