High‐yield synthesis of para ‐substituted pentacarbonyl(3‐phenyl‐2 H ‐azaphosphirene)tungsten complexes is reported, using a multi‐step rearrangement reaction. Spectroscopic and mass‐spectrometric data of these heterocyclic complexes are discussed; the 31 P‐NMR‐chemical shifts clearly reflect the electronic influence of the para ‐phenyl substituents and the correlation with Hammett σ p ‐constants is almost linear.
