Phenylimido Complexes of Tungsten IV

L = PMejPh, PMePhz, PEt3, PMe3, Me3CNC, p-MePhNC 

The complexes prepared in this manner are blue or brown and are air- and moisture-sensitive. However, they can be stored for several months under N2. They are diamagnetic and soluble in most organic solvents except petroleum ether and similar hydrocarbons. In the far-IR spectrum, several absorption bands occur in the vicinity of 250-300 cm. These are assigned to V(m cd- The X-ray crystal structure of WCl2(PhN)(PMe3)3 shows a mer arrangement of phosphine and cis chloride ligands, one Irons to the phenylimido function.
