Transition Metal Stannyl Complexes, 7. - Preparation of Carbene Complexes (?-Arene)(CO)2CrCR2 by the Reaction of the Anionic Stannyl Complexes - with R2CX2 or Y

Carbene complexes (?-arene)(CO)2Cr=CR2 are formed in substitution/elimination reactions from the anionic stannyl complexes K and organic dihalides R2CX2 containing activated C-X bonds or ionic halides Y.Bis(stannyl)complexes (?-arene)(CO)2Cr(SnPh3)2 (3) and hydrido(stannyl)complexes (?-arene)(CO)2Cr(H)SnPh3 are formed as byproducts due to the reaction of the eliminated Ph3SnCl with the anionic starting complexes or electron transfer reactions, respectively.The portion and ration of the byproducts is largely influenced by the steric properties of both the (?-arene)(CO)2Cr fragment and the organic halide.Pyridinylidene complexes 2 are only obtained from 2-chloro-N-methylpyridinium tetrafluoroborate with 1a-c, but not with 1d.With the sterically less demanding halides Cl (n=3,4)> or 3,3-dichloro-1,2-diphenylcyclopropene the carbene complexes (?-arene)(CO)2Cr=C(H)NR2 or are obtained with all employed ?-arene ligands.
