1-silatranes, NH2(CH2)2NH(CH2)n-Si(OCH2CH2)3N- (I, n=1; III, n=3) and their paramagnetic complexes with CuCl2 (2:1) (III and IV) have been synthesized.Relevant 1H and 13C NMR data reveal, that the molecule I in the series of silatranes has the weakest transannular Si0 fast atom bombardment (FAB) mass spectra indicates that the Si-N bond in their molecules is stronger than those in the initial silatranes I and II.

The invention relates to a preparation method of alpha-amino triethoxysilane. The method comprises the following steps: (1) dissolving sodium ethoxide in a sufficient amount of organic solvent, then uniformly dropwise adding the sodium ethoxide solution into chloromethyl trichlorosilane, allowing the raw materials to react for a period of time at normal temperature after the dropwise addition is completed, carrying out normal pressure distillation to remove ethanol and insoluble substances to obtain chloromethyl triethoxysilane; (2) heating organic amine under the protection of nitrogen until boiling, and then dropwise adding the chloromethyl triethoxysilane prepared in the step (1), allowing the raw materials to react for 1-8 hours at the temperature of 70-200 DEG C after the dropwise addition is completed; filtering the reactant to remove the generated salt after the reaction is ended, distilling at normal pressure to remove the low-boiling-point substance, and then collecting the product at a proper boiling point under reduced pressure distillation, so that the alpha-amino triethoxysilane is obtained. According to the invention, no additional acid absorbent needs to be added, organic solvent is not added, so that the subsequent separation is simple, and the generation of by-products such as polysubstituted compounds of organic amines is less, the utilization rate of the amine is relatively high, and the side reaction of the reaction system is easy to control; the product purity can reach more than 95%, and the yield is over 40%.
