Abstract

Abstract A reasonably stabilized trichloromethyl anion (TCMA) was formed by the reaction of chloroform with an electrogenerated base prepared by the electroreduction of 2-pyrrolidone, and the addition of this TCMA to α, β-unsaturated esters gave the corresponding β- trichloromethyl esters in good yields.
