The interaction of lithium acylates -carbanions (obtained via metallation of acetic, butyric, and isobutyric acids with lithium diisopropylamide) with 1,2-diiodoethane under argon in tetrahydrofuran at 20-25 degrees C has proceeded as oxidative cross-coupling of enolate anions to form succinic, 2,3-diethylsuccinic, and 2,2,3,3-tetramethylsuccinic acids with yields 50, 53, and 16%, respectively. The products of sequential nucleophilic substitution of iodine atoms with alkyloxycarbonyl species have not been detected.
