Abstract

In an attempt to form a group 10 'carbenoid' derivative by double deprotonation of the N-mesityl substituted bis(phosphinimino)methane [CH₂(Ph₂P{double bond, long}N-2,4,6-Me₃C₆H₂)₂], reaction with [PdCl₂(MeCN)₂] yielded a singly metallated dichloropalladate(II) complex as the only product. This was completely characterised specroscopically and by single crystal crystal X-ray diffraction. In contrast, reaction of [CH₂(Ph₂P{double bond, long}N-2,4,6-Me₃C₆H₂)₂] with [PtMe₂(COD)] produced a bis(phosphinimino)methanide complex, which had also undergone ortho-metallation of two P-phenyl groups to effect a triple C-H activation reaction.
