Reaction of phenyltrifluorosilane, diphenyldifluorosilane, and methylphenyldifluorosilane with bis(2-hydroxyethyl)amine, methyl-bis(2-hydroxyethyl)amine, methyl-bis(2-trimethylsiloxyethyl)amine, leads to 1,3-dioxa-6-aza-2-silacyclooctane derivatives, (N -> Si) quasisilatranes: 1,1-difluoroquasisilatrane, 1-phenyl-1-fluoro-5-methylquasisilatrane, or 1-methyl-1-fluoroquasisilatrane, containing the donor-acceptor bond N -> Si and pentacoordinate silicon atom. 1-Phenylsilatrane was found to be the product of the reaction of phenyltrifluorosilane with tris(2-trimethylsiloxyethyl)an-ne, whereas with tris(2-hydroxyethyl)amine 1-phenylsilatrane and 1-fluorosilatrane were formed in the molar ratio of 3: 1. The structure of the synthesized compounds was proved by H-1, C-13, N-15, F-19, Si-29 NMR and IR spectroscopy.
