Abstract

Results In a first series of experiments the a-bromo ester 2 was electrolyzed in the presence of the carbonyl compounds la-n at an external voltage of 30 V and a temperature of 50" C (Scheme 1). All these experiments were performed withDMF/THF (1: 2) as solvent and tetrabutylammonium bromide as supporting electrolyte in an undivided cell e Abstract published in Aduance ACS Abstracts, April 15, 1994.(1) Reactions of Electrochemically ...
