Abstract
Communications to the Editor 4 suggest that this molecule should be viewed similarly. Its properties are more consistent with an ylide-type adduct of PPh, to nitrene 2 than with a coordinated phosphinimine that retains a phosphorus-nitrogen double bond. The values of vco for the (CO), W unit of 46 strongly resemble those for zwitterion 1 (2061, 1913, 1860 cm- I) and carbene ylide 513 (2051, 1950, 1909, 1871 cm-I) suggesting similar amounts of ...
