Abstract : Significant contributions to the understanding of the synthesis, structure and reactivity of d4 and d6 metal carbene complexes of the type Cp(CO)(L)Fe=CHR+ (R=aryl, alkyl; L=P(C6H5)3, CO) and Cp(CO2)LM=CHR+ (M=Mo,W; R=H, aryl) are described. The increasing interest in these complexes can be attributed to their unique reactivity patterns and to their potential importance as intermediates in catalytic processes (olefin metathesis, polymerization and carbene transfer reactions). Recent studies of the cyclopropanation of styrene have provided an excellent model for establishing the role of metal chirality in the conversion of prochiral substrates into optically-active products.
