Indium(III) Halide Mediated S _N 2′ Reactions of Substituted Allenols: Synthesis of 2-Halo-1,3-dienes

Abstract

Treatment of various substituted allenols with indium(III) halide in benzene gave (Z)- or (E)-2-halo-1,3-dienes in moderate to good yields. In most cases, (2Z)-halo-1,3-dienes were obtained as major products.

Key words

allenol - indium(III) halide - 2-halo-1,3-diene - S_N2′ reaction
