Regioselective chelation in the reaction of N-trimethylsilyl-N-acetylglycine N’,N’-dimethylamide with chloro(chloromethyl)dimethylsilane
2015
Regioselective reaction of N -trimethylsilyl- N -acetylglycine N’ , N’ -dimethylamide with chloro(chloromethyl)dimethylsilane yields chlorosilane MeC(O)N(CH 2 SiMe 2 Cl)CH 2 C(O)NMe 2 with a five-membered C,O-chelate ring involving the N -acetyl group rather than the six-membered ring involving the N’ , N’ -dimethylamide fragment. According to X-ray data, the pentacoordinate silicon atom in the product has a TBP environment with the halogen and oxygen atoms in axial positions.
