Abstract

(Et2N)3 P=CH2 reacts with NbCl5 , WCl6 or WF6 under C-C bond formation to give the phosphonium cation [(Et2N)3 PCH2]2 2+ · [(Et2N)3PCH2]22+ [WCl6 ]2 - was isolated in a crystalline form and investigated by X-ray analysis. The reaction of (Et2N)3 P=CH2 with MOCl4 in a solvent proceeds with formation of the [(Et2N)3 PCH ]+ cation.
