Reaction of Tetrafluorosilane with Tris(2-hydroxyethyl)amine, Tris(2-trimethylsiloxyethyl)amine and Bis(2-trimethylsiloxyethyl)amine and Its iV-methyl Derivative.1,1-Difluoroquasisilatranes

摘要

Reaction of tetrafluorosilane with tris(2-hydroxyethyl)- and tris(2-trimethylsiloxyethyl)amine results in formation of 1-fluorosilatrane and fluorosilatrane in 75 and 53% yield,respectively.Reaction of tetrafluorosilane with bis(2-trimethylsiloxyethyl)amine and its N-methyl derivative leads to the hitherto un-known 1,1-difluoroquasisilatranes(N->Si)F2Si(OCH2CH2)2NR(R = H,Me)containing donor-acceptor bond N->Si and pentacoordinate silicon atom.The structure of the synthesized compounds was proved by 1H,13C,15N,19F,29Si NMR and IR spectroscopy.
