Synthesis of Amines from Imines in the Coordination Sphere of Silicon-Surprising Photo-Rearrangement of Hexacoordinate Organosilanes

There's room at the top: In the coordination sphere of hexacoordinate organosilanes with O‐ and N‐donor ligands (see picture) the SiC bond is elongated and activated. This effect is so strongly pronounced that cleavage of one SiC bond and migration of this organo substituent takes place upon...

Zusammenfassung:There's room at the top: In the coordination sphere of hexacoordinate organosilanes with O‐ and N‐donor ligands (see picture) the SiC bond is elongated and activated. This effect is so strongly pronounced that cleavage of one SiC bond and migration of this organo substituent takes place upon irradiation with UV light to give a pentacoordinate silicon complex.
