sterically demanding nucleophiliccarbenes 1,3-bis(2,6-dimethyl-4-bromophenyl)imidazol-2-ylidene (1) and 1,3-dimesitylimidazol-2-ylidene (3) with manganocene resulted in complexes of the type (η2-C5H5)(η4-C5H5)Mn(carbene) (2 and 4). The reaction of equimolar amounts of the less sterically demanding nucleophiliccarbene tetramethylimidazol-2-ylidene (5) afforded the bis(carbene)complex (η1-C5H5)(η2-C5H5)Mn(carbene)2
