Recently Krapcho and Lovey have reported that germinal diesters, B-keto esters and a-cyano esters undergo decarbalkoxylatlons when heated with sodium chloride In wet dimethyl eulfoxide at temperatures of 140-185' (1). We now wish to report further experiments addressed to the question of whether add
