Reaction of transition metal “frustrated”
Lewis pair compounds of the type [Cp2Zr(Me)(OC(CF3)2CH2PtBu2)] with the
low valent platinum species [Pt(norbornene)3] leads to
the unexpected formation of a heterobimetallic species [Cp2Zr{Pt(Me)}(OC(CF3)2CH2PtBu2)]. Single crystal
X-ray analysis reveals an unusual T-shaped geometry at the platinum
center, with a relevant C–Pt–P angle of 163.3(3)°.
Treatment of this compound with PMe3 yields [Pt(PMe3)4] and regenerates the zirconium precursor. Treatment
with [(Et2O)2H][B(C6F5)4] protonates off the methyl ligand to give an ether
adduct at platinum. Analogous observations are made with titanium–platinum
species. We propose the chemistry is best rationalized as a formal
insertion of Pt(0) into a Zr–C or Ti–Cl bond.
