Organomagnesium amide catalyzed cross-dehydrocoupling of organosilanes with amines

Abstract

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-Me₂C₆H₃ (Xyl) (1) and 2,4,6-Me₃C₆H₂ (Mes) (2) is reported. Both compounds 1 and 2 were confirmed by multinuclear (¹H, ¹³C and ²⁹Si) 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.
