Coordination Behavior of [Cp''2Zr(h1:1-P4)] towards Different Lewis Acids

摘要

A detailed method for the preparation of [Cp''_2Zr(η~(1:1)-P_4)] (1) is presented. The coordination behavior of 1 towards Lewis acidic transition metal complexes of tungsten, manganese, and iron, respectively, and main group compounds (AlMe_3, AlEt_3) was investigated in detail by computational and experimental studies. In doing so, a series of unprecedented complexes with different coordination modes and multiple coordination numbers of the tetraphosphabicyclo[ 1.1.0]butane framework were synthesized. All products, as well as the starting materials, were comprehensively characterized by NMR spectroscopy, mass spectrometry, elemental analysis, and single crystal X-ray structural analysis.
