Treatment of
Cp(CO)(SnMe<sub>3</sub>)Fe{PN(Me)CH<sub>2</sub>CH<sub>2</sub>NMe(OR)} (R = Me, Et) with
Me<sub>3</sub>SiOSO<sub>2</sub>CF<sub>3</sub>
(TMSOTf) yields
[Cp(CO)(SnMe<sub>2</sub>)Fe{PN(Me)CH<sub>2</sub>CH<sub>2</sub>NMe(Me)}]OTf (<b>2</b>), showing that P−OR bond cleavage
and
Me migration from Sn to P take place. The X-ray
analysis of <b>2</b> reveals that this is a stannylene
complex
of iron stabilized by both an OTf<sup>-</sup> anion and an N
atom
in the phosphorus ligand. In solution, <b>2</b> is in
equilibrium with an OTf-dissociated species.
