Group 1 acyl metal compounds are relatively unstable and highly reactive and so it has not been possible to characterise such a compound. One plausible mechanism for the formation of these products involves the intermediacy of an acyl anion. A proposed intermediate is the ethylene-propionyl species [CH 3 C (O)Co (CO) 3 (ethylene)] which undergoes a migratory insertion to form [CH 3 COCH 2 CH 2 Co (CO) 3 ]. The synthetic utility of acyllithium compounds in intermolecular reactions is relatively limited due to the restricted range of acyllithium species available by current methods.
