Аннотация:The reaction of dialkanolamines RN(CH(2)CH(2)O)(CHR'CHR'OH) (R = Me, Ph, PhCH(2); R' = H, Ph) with tetraethoxygermane gives either 2,2-diethoxy-1,3,6,2-dioxazagermocanes RN(CH(2)CH(2)O)(CHR'CHR'O) Ge(OEt)(2) or 1,7,9,15-tetraoxa-4,12-diaza-8-germaspiro[7.7] pentadecanes [RN(CH(2)CH(2)O) (CHR'CHR'O)](2)Ge depending on the reactant ratio. The chemical behavior of the obtained compounds in substitution reactions at germanium was studied. The product structure was confirmed by elemental analysis data and (1)H, (13)C, and (19)F NMR spectroscopy. The cyclotrigermanoxane [MeN(CH(2)CH(2)O)(2)GeO](3) was studied by X-ray diffraction.
