Direct Synthesis of trans-1,4-Diacetoxycyclohexa-2,5-diene by Electrochemical Reduction of r-1,t-4-Diacetoxy-t-2,c-3-dibromocyclohex-5-ene

Abstract

Electrochemical reduction of r-1,t-4-diacetoxy-t-2,c-3-dibromocyclohex-5-ene 1 gives only trans-1,4-diacetoxycyclohexa-2,5-diene 2 in good yield while the commonly used Zn reduction gives a product mixture containing 2 and acetoxybenzene 3 derived from acetoxy elimination.
