The present invention relates to a method for preparing silicon-containing heterocycles of the general formula (I), wherein R1 is hydrogen; R2 and R3 are same or different and are, independently from one another, selected from a linear or branched, substituted or unsubstituted C1-C20 alkyl or C6-C18 aryl residue which may be interrupted by at least one heteroatom; R4 is selected from a linear or branched C1-C20 alkylene residue which may be interrupted by at least one heteroatom; R5 and R6 are same or different and are, independently from one another, selected from the group consisting of hydrogen, a linear or branched, substituted or unsubstituted C1-C20 alkyl or C6- C18 aryl which may be interrupted by at least one heteroatom, and a C4-C8 cycloalkyl, or R5 and R6 may form a ring, preferably a 4- to 8-membered alkyl ring; and n is 0, 1 or 2, preferably 2, said method comprising a one-step reaction of at least one epoxide compound of the general formula (II) and at least one aminoalkoxysilane having a primary amino group in the presence of a catalyst formula (II), wherein R5 and R6 are the same as defined for the general formula (I) above; as well as the use of the silicon-containing heterocycles of the general formula (I).
本发明涉及一种制备通式(I)中含硅杂环化合物的方法,其中R1为氢;R2和R3相同或不同,分别选择自一种线性或支链的取代或未取代的C1-C20烷基或C6-C18芳基残基,其可以被至少一个杂原子中断;R4选择自一种线性或支链的C1-C20烷基残基,其可以被至少一个杂原子中断;R5和R6相同或不同,分别选择自氢、一种线性或支链的取代或未取代的C1-C20烷基或C6-C18芳基,其可以被至少一个杂原子中断,以及一种C4-C8环烷基,或者R5和R6可以形成环,优选为4-至8-成员烷基环;n为0、1或2,优选为2,所述方法包括在催化剂的存在下,至少一种通式(II)的环氧化合物和至少一种具有主要氨基团的氨基烷氧基硅烷的一步反应,其中R5和R6与上述通式(I)中定义的相同;以及使用通式(I)中的含硅杂环化合物。
