Abstract

Abstract When BrMn(CO) 5 and the rhenium complexes, XRe(CO) 5 (where X is H, Cl, Br or I) are treated with one equivalent of methyllithium the corresponding cis-halo- or hydrido-acetylmetalate complexes, Li[ cis-(OC) 4(X)MC(O)CH 3], are formed unexpectedly. The protonation of the halo-anions affords the hydroxy-carbenoid complexes. When the halopentacarbonylrhenium complexes are treated with Li[BEt 3H] the corresponding formylmetalate complexes are formed. The reaction chemistry of these anions and of the analogous formyl- and acetyl-metalate anion is discussed briefly.
