(N-heterylmethyl)trimethoxy- and (N-heterylmethyl)dimethoxymethylsilanes

(Chloromethyl)trimethoxy- and (chloromethyl)dimethoxymethylsilane were reac ted with N-sodium salts of imidazole, 3,5-dimethylpyrazole, indole, benzimi dazole, and phthalimide to obtain the corresponding (N-heterylmethyl)trimet hoxy- and (N-heterylmethyl)dimethoxymethylsilanes. Trasetherification of (N -heterylmethyl)trimethoxysilanes with triethanolamine gave previously unkno wn 1-(N-heterylmethyl) silatranes. The first synthesis of poly(N-heterylmet hyl)silsesquioxanes was performed by hydrolysis of (N-heterylmethyl)trimeth oxysilanes.
