Abstract

Catalytic intramolecular cyclization of 3-aminopropylalkoxysilanes and 3-aminopropylalkoxydisiloxanes in the presence of hexamethyldisilazane has been studied; structure and reactivity of the formed azasilacyclopentanes have been investigated. In particular, the prepared cyclic azasilanes were studied by 1H, 29Si, and 13C NMR spectroscopy. Possibility of catalytic co-condensation of the compounds containing methoxy and trimethylsiloxy groups with preservation of azasilacyclopentane structure has been demonstrated. Depending on temperature and the reactants ratio, the interaction of 3-aminopropylmethyldimethoxysilane with hexamethyldisilazane can yield 1-(trimethylsilyl)-2-methyl-2-methoxy-1-aza-2-silacyclopentane or the polymer bearing azasilacyclopentane fragments in the main chain.
