1-Organyl-2-azasilatran-3-ones

New 1-organyl-2-azasilatran-3-ones have been synthesized via the reaction of trifunctional silanes RSiX₃ (R = Et, Pr, Ph, CH₂=CH, or ClCH₂; X = Cl or Me₂N) with N,N-bis(2-hydroxyethyl)glycinamides (HOCH₂CH₂)₂NCH₂C(O)NHR (R = H or Me) and their N′,O-trimethylsilyl derivatives. The obtained products can be hydrolyzed to give the corresponding organylsilanetriols. Lithiation of 1-methyl- and 1-phenyl-2-azasilatran-3-ones with n-butyllithium or their reduction with lithium aluminum hydride leads to the products of splitting of the atrane backbone RSiBu₃ and RSiH₃ (R = Me or Ph), respectively.
