通过取代三烷氧基硅烷与三乙醇胺的酯交换反应合成了４个１－取代杂氮硅三环．以氯丙基杂氮硅三环与亚磷酸酯进行Ａｒｂｕｚｏｖ反应得到２个含磷酰基的杂氮硅三环．氨丙基杂氮硅三环与芳醛的缩合反应得到４个含芳亚甲氨基丙基的杂氮硅三环化合物．对所合成化合物的结构进行了表征，并对反应条件作了初步探讨 Four 1-substituted azasilanes were synthesized by transesterification of substituted trialkoxysilanes with triethanolamine. The Arbuzov reaction of chloropropyltrizosilane with phosphite gave two phosphoryl-containing heterocycles. The condensation reaction of the aminopropylsilazane tricyclic ring with the aromatic aldehyde gives four azido tricyclic compounds containing an aromatic methylene aminopropyl group. The structures of the synthesized compounds were characterized and the reaction conditions were preliminarily discussed
