Enthalpy-Controlled Insertion of a "Nonspectator" Tricoordinate Phosphorus Ligand into Group 10 Transition Metal-Carbon Bonds.

ABSTRACT: Insertion of a tricoordinate phosphorus ligand into late metal-carbon bonds is reported. Metalation of a P^P-chelating ligand (L1), composed of a nontrigonal phosphorous (i.e., P(III)) triamide moiety, P(N(o-N(Ar)C₆H₄)₂, tethered by a phenylene linker to a -PⁱPr₂ anchor, with group 10 complexes L₂M(Me)Cl (M = Ni, Pd) results in insertion of the nontrigonal phosphorus site into the metal-methyl bond. The stable methylmetallophosphorane compounds thus formed are characterized spectroscopically and crystallographically. Metalation of L1 with (cod)Pt^II(Me)(Cl) does not lead to a metallophosphorane but rather to the standard bisphosphine chelate (κ²-L1)Pt(Me)(Cl). These div
