Reactivity of an N-mesityl bis(phosphinimino)methane with group 10 metals
摘要:
In an attempt to form a group 10 'carbenoid' derivative by double deprotonation of the N-mesityl substituted bis(phosphinimino)methane [CH2(Ph2P=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=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.
