Allyl(pyridine)cobaloximes RCo(dmgH)2Py (R = allyl) react readily with diethyldibromomalonate, diethylbromomethylmalonate and ethyl 2-bromoacetoacetate to give the corresponding allyl-substituted esters.Transfer of the allyl group occurs with complete rearrangement in all but one cases.Buten-3-yl(pyridine)cobaloximes react with diethylbromomalonate giving cyclopropylmethylmalonic esters.
