摘要

在1-异丙基-2-苯基-1，2，5，6-四氢苊并[5，6-cd][1，2]二磷存在下，通过六羰基钨的光解，制备了具有不对称桥接1,2-二磷配体的双核钨（0）配合物。钨配合物1通过高分辨率质谱、多核NMR光谱（1H，13C，31P）和元素微量分析进行了表征。通过单晶X射线衍射解析了反式异构体的结构，显示出P−P键在与W（CO）5基团配位时的轻微伸长。

(Decacarbonyl)(1-isopropyl-2-phenyl-1,2,5,6-tetrahydroacenaphtho [5,6-cd][1,2]diphosphole)ditungsten(0)

A binuclear tungsten(0) complex with an asymmetric bridging 1,2-diphosphole ligand was prepared by the photolysis of tungsten hexacarbonyl in the presence of 1-isopropyl-2-phenyl-1,2,5,6-tetrahydroacenaphtho [5,6-cd][1,2]diphosphole. The tungsten complex 1 was characterized by high resolution mass spectrometry, multinuclear NMR spectroscopy (1H, 13C, 31P), and elemental microanalysis. The structure of the trans isomer was resolved by single crystal X-ray diffraction, showing a slight elongation of the P−P bond upon coordination to the W(CO)5 groups.
