Organomagnesium amide catalyzed cross-dehydrocoupling of organosilanes with amines.

The synthesis of novel heteroleptic organomagnesium(ii) amide complexes [IMesMg(Ar){N(SiMe3 )2 }]; (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene), Ar = 2,6-Me2 C6 H3 (Xyl) (1) and 2,4,6-Me3 C6 H2 (Mes) (2) is reported. Both compounds 1 and 2 were confirmed by multinuclear (1 H,13 C and29 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.
