title: Coupling of coordinated 2-iminophosphorano-1-phosphaallyl leading to bridged iminophosphoranato complexes of zirconium and hafnium.
abstract: Reaction of MCl4 (M = Zr, Hf) with 2 equiv of 2-iminophosphorano-1-phosphaallyl lithium [Li[P(Ph)C(=CHPh)P(Me)2=NSiMe3](THF)1.5] (1) affords ligand coupling complexes 3 and 4, respectively, while similar treatment of ZrCl4 with [Li[P(Ph)C(=C(SiMe2Bu(t))Ph)P(Me)2=NSiMe3](THF)2] (2) yields ligand transfer complex 5.
