M. Tokuda et al., REGIOSELECTIVE SYNTHESIS OF BETA,GAMMA-UNSATURATED ACIDS BY THE ELECTROCHEMICAL CARBOXYLATION OF ALLYLIC BROMIDES USING A REACTIVE-METAL ANODE, Tetrahedron letters, 36(19), 1995, pp. 3345-3348
Electrolysis of gamma-mono and disubstituted allylic bromides in the p
resence of atmospheric pressure of carbon dioxide using a platinum cat
hode and a magnesium anode gave regioselectively the corresponding gam
ma-mono and disubstituted beta,gamma-unsaturated carboxylic acids in 3
4-71% yields.
