Reaction of either of two isomers of or either of two isomers of <2> with SnBu3(C3H5) yields a single isomer of .A mechanism involving the intermediate formation of the five-co-ordinate species and is proposed for the reactions.Treatment of complexes <2> (L = phosphorus or arsenic ligand) with SnBu3(C3H5) yields the related complexes , and the method can be extended to the preparation of 1-methylallyl and 2-methylallyl complexes.Simulation of the complex (1)H n.m.r. spectra of and its AsMe2Ph analogue provides detailed information about the coupling between the protons in the allyl ligand.Treatment of with excess of PMe2Ph results in the formation of , which is very slowly converted in solution into : the key intermediate in the system appears to be .
