(Amidomethyl)dimethylsilanol hydrohalides: Synthesis, NMR and IR studies. Characteristic features of the electronic structure from high-resolution X-ray study and quantum chemical calculation

(C,O)-chelate silanol hydrohalides RC(O)NHCH2SiMe2OH · HHal, their precursors, chlorides RC(O)NHCH2SiMe2Cl and disiloxanes [RC(O)NHCH2SiMe2]2O were obtained by several routes. The original scheme of hydrolysis of the above chlorides was discussed in detail. The electron structure of silanol hydrohalides have been investigated using high-resolution X-ray study and quantum chemical calculations.
