摘要

合成了一种新的不对称PCN钳形配体n -乙基- n -[3-（（2,3,4,5-四苯基- 1h -磷酸-1-基）甲基）苄基]乙胺，结合了不同的给基（氨基和磷孔）。该配体由市售试剂分四步获得，总收率（49%）较高。在此基础上，提出了不对称镍螯合物的设计。配合物分子结构的量子化学计算表明，形成了弱的Ni-P键，并揭示了相对于氨基的弱反式影响，这将该配合物与基于二烷基膦的PCN配合物区别开。

Design of an Asymmetric PCN Pincer Nickel(II) Complex Based on 2,3,4,5-Tetraphenyl-1-monophosphole

A new asymmetric PCN pincer ligand, N-ethyl-N-[3-((2,3,4,5-tetraphenyl-1H-phosphol-1-yl)methyl)benzyl]ethanamine, combining different donor groups (amino and phosphole), has been synthesized. The ligand was obtained in four steps with a good overall yield (49%) from commercially available reagents. Based on this ligand, the design of an asymmetric nickel(II) pincer complex was proposed. Quantum chemical calculations of the molecular structure of the complex indicate the formation of weak Ni–P bonds and reveal a weak trans influence of the phosphole group relative to the amino group, which distinguishes this complex from its analogs, PCN complexes based on dialkylphosphines.
