An efficient and safe method is proposed for the preparation of an oximesilane compound having a group of the general formula -0-N = CR²R³, in which R² and R³ are each a hydrogen atom or a monovalent hydrocarbon group, bonded to the silicon atom. The method consists of successive steps of which the first is for the reaction of a chlorosilane compound with ammonia and the second is for the reaction of the reaction mixture coming from the first step with an oxime compound to introduce the oxime groups as bonded to the silicon atom. Different from conventional methods in which formation of an explosive compound such as hydrochloride of an organic base or oxime compound is unavoidable, the inventive method does not involve formation of such an explosive by-product so that the desired oximesilane compound can be obtained without the danger of explosion.
本发明提出了一种高效安全的方法,用于制备具有通式 -0-N = CR²R³ 基团的
肟基
硅烷化合物,其中 R² 和 R³ 各为一个氢原子或一个与
硅原子结合的一价烃基。该方法由多个步骤组成,其中第一个步骤是
氯硅烷化合物与
氨反应,第二个步骤是将第一个步骤产生的反应混合物与
肟化合物反应,以引入与
硅原子结合的
肟基团。传统方法不可避免地会形成爆炸性化合物,如有机碱或
肟化合物的盐酸盐,而本发明的方法则不同,不会形成这种爆炸性副产品,因此可以在没有爆炸危险的情况下获得所需的
肟基
硅烷化合物。
