Lithioxy carbene

Jutzi reported the formation of enediol compounds from the reaction of trimethyl-silyl lithium with CO (Eq. (5.51)) [56]. As shown above, they proposed a mechanism involving the dimerization of a lithioxy carbene, which is an acyllithium tautomer (Eq. (5.51)). A similar reaction suggests the possibility of further insertion... 

The structure of acyllithium has not yet been established experimentally. A priori, three types of structures can be envisioned. These are acyllithium (or 1/ -acyllithium), / -acyllithium and lithioxy carbene. For the case of lithioxy carbene, the...
