Me3SiOSO2CF3 (TMSOTf) yields [Cp(CO)(SnMe2)FePN(Me)CH2CH2NMe(Me)}]OTf (2), showing that P−OR bond cleavage and Me migration from Sn to P take place. The X-ray analysis of 2 reveals that this is a stannylene complex of iron stabilized by both an OTf- anion and an N atom in the phosphorus ligand. In solution, 2 is in equilibrium with an OTf-dissociated species.
