(O-Si)-chelate N-(dimethylhalogenosilylmethyl) acetamides, MeC(O)N(CH(Ph)Me)CH2SiMe2 X (X = F, Cl), obtained are the model compounds in studies of the stereodynamic processes at the trigonal-bipyramidal silicon atom and asymmetric induction. An X-raystructural investigation confirmed a 3 + 2 pentacoordination of the Siatom in the title compounds and an axial arrangement of the oxygen and halogen atoms. The
