资源简介：
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)PtII(Me)(Cl) does
not lead to a metallophosphorane but rather to the standard bisphosphine
chelate (κ2-L1)Pt(Me)(Cl). These divergent
reactivities within group 10 are rationalized by reference to periodic
variation in M–C bond enthalpies.
