Anions of the type [(η5-C5H5)(CO)(L)(M4BPh 3)MT]- (L = CO, NO; M4B - Si, Ge, Sn; MT = Mn, Mo, W) react with allyl halides, affording neutral σ-bonded alkenyl derivatives. These new complexes can rearrange to η3-allyl complexes and also lose (allyl)M4B to give η2-allyl complexes. According to the nature of both the transition metal and the group 4B metal η1, η3, or η2 complexes are obtained. A mechanism for these successive reactions is proposed. Butenyl and hexenyl iodides also react with the anions, affording η1 complexes that can eliminate CO and rearrange to a η3 ligand as shown by X-ray structure determination.
