High-yield synthesis of para-substituted pentacarbonyl(3-phenyl-2H-azaphosphirene)tungsten complexes is reported, using a multi-step rearrangement reaction. Spectroscopic and mass-spectrometric data of these heterocyclic complexes are discussed; the 31P-NMR-chemical shifts clearly reflect the electronic influence of the para-phenyl substituents and the correlation with Hammett σp-constants is almost
报道了使用多步重排反应合成对位取代的五羰基(3-苯基-2H-氮杂膦)钨配合物的高产率。讨论了这些杂环配合物的光谱和质谱数据;31P-NMR 化学位移清楚地反映了对苯基取代基的电子影响,并且与 Hammett σp 常数的相关性几乎是线性的。
