ELECTROCHEMICAL CARBOXYLATION OF alpha , beta -UNSATURATED KETONES WITH CARBON DIOXIDE.

Abstract

Several aromatic and aliphatic alpha , beta -unsaturated ketones were converted to the corresponding gamma -keto acids by the electrochemical reduction in acetonitrile in the presence of CO//2. The yields of the keto acid were 73-82% when the enones have at least one aromatic substituent. In the case of aliphatic enones, the yields of the carboxylation reaction were 67% for 2-cyclohexen-1-one and 44% for 3-buten-2-one.
