摘要

Abstract: Catalytic isomerization of alkynes to allenes under phase-transfer catalyzed conditions is described. Commercially available quaternary ammonium salt such as tetrahexylammonium bromide acts as a very effective promoter to accelerate the reaction under mild conditions. Key words: allenes, asymmetric reactions, catalysts, isomerization, phase-transfer
