High yields in the alkylation of dianions of ex,l~-unsaturated carboxylic acids with secondary halides can be obtained despite elimination reactions occurring, cx-Regioseleetivity for the alkylation of but-2-enoic acids (1-4) is seldom obtained. Although double bond stereoselectivity is higher than
