Copper-catalyzed decarboxylative and oxidative decarbonylative cross-coupling between cinnamic acids and aliphatic aldehydes

Abstract

A convenient copper-catalyzed decarboxylative and oxidative decarbonylative cross-coupling of cinnamic acids with aliphatic aldehydes was achieved, which provides a useful strategy of C(sp³)–C(sp²) bonds construction for the synthesis of alkyl-substituted <italic>E</italic>-alkenes.
