The reaction of organolithium compounds with oxalyl derivatives and cyclic 1,2-dicarbonyl compounds leads to pinacols or ketones derived from homolytic C-C bond cleavage of the intermediate O,O-centered pinacol dianions depending on the ability of the substituents for the stabilisation of the resulting radical anion.The homolysis is induced by electrostatic repulsion of the negatively charged oxygen atoms.
