大体积的三（卡宾）硼酸盐配体提供了获得高自旋铁（II）膦基络合物的途径。配合物PhB（MesIm）（3）FeP（H）Ph是热不稳定的，[PPh]基团插入到支持配体的C-H键中。一个被捕的α-氢化物迁移机制表明，磷原子的亲核性增加促进[PPh]基团转移反应。
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 alpha-hydride migration mechanism suggests increased nucleophilicity of the phosphorus atom facilitates [PPh] group transfer reactivity.
