Arrested α-hydride migration activates a phosphido ligand for C–H insertion. Issue 2 (13th December 2016) - Hickey, Anne K.
Abstract : Arrested α-hydride migration increases the nucleophilicity of the phosphorus atom in a phosphido ligand, facilitating [PR] group transfer reactivity. Abstract : Bulky tris(carbene)borate ligands provide access to high spin iron(ii ) phosphido complexes. The complex PhB(MesIm)3 FeP(H)Ph is thermally unstable, and [PPh] group insertion into a C–H bond of the supporting ligand is observed. An arrested α-hydride migration mechanism suggests increased nucleophilicity of the phosphorus atom facilitates [PPh] group transfer reactivity.
