The synthesis of C-2,4,6-trialkylphenyl-substituted ethoxy- and aminocarbene tungsten complexes 1a-c (R = Me, iPr and tBu) and 2a,b (R = Me, iPr) and the reaction of 2a,b with [bis(trimethylsilyl)methylene]chlorophosphane (3) in the presence of triethylam

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 linear.
