SYNTHESIS AND CHARACTERIZATION OF 3-ETHYLSILATRANES
摘要:
A series of 1-Organyl-3-ethylsilatranes, RSi(OCHEtCH2)(OCH2CH2)(2)N, where R= H2N(CH2)(3)-, H2N(CH2)(2)NH(CH2)(3)-, H2N(CH2),NH(CH2)(2)NH(CH2)(3)-, Cl(CH2)(3)-, CH2=CH-, CH3CONH(CH2)(3)-, H2NCONH(CH2)(3)-, C6H9O(CH2)(2)-, C3H5N2(CH2)(3)-, C3N3O3(CH2CH2-CH2)(3)- have been synthesised in yields ranging from 79 to 93% by transesterification of corresponding 1-organyltrialkoxysilanes with bis(2-hydroxyethyl)-2-hydroxybutylamine, These silatranes have been characterized by elemental analyses, IR, H-1 and C-13 NMR spectroscopy.
