Organomagnesium amide catalyzed cross-dehydrocoupling of organosilanes with amines.

The synthesis of novel heteroleptic organomagnesium(ii) amide complexes [IMesMg(Ar){N(SiMe)}]; (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene), Ar = 2,6-MeCH (Xyl) (1) and 2,4,6-MeCH (Mes) (2) is reported. Both compounds 1 and 2 were confirmed by multinuclear (H, C and Si) magnetic resonance spectroscopy, elemental analysis and single crystal X-ray structural analysis. Furthermore, the organomagnesium amide pre-catalyzed cross-dehydrogenative coupling of organosilanes with amines has been investigated.
