The present invention is a silylating method employing of formula (CH.sub.3)(R)(R.sup.1)SiX ; where R is an isopropyl group, R.sup.1 is a monovalent hydrocarbon group having 2 to 6 carbon atoms, and X is a chlorine atom or bromine atom. The silylating agent of the present invention provide silylation product which is much more stable than the silylation product obtained with trimethylchlorosilane, and its protective group is as stable as the silylation product obtained from t-butyldimethylchlorosilane. Moreover, the present described silylating agents are characterized by an easier desilylation than the t-butyldimethylsilyl group.
本发明是一种使用式(CH.sub.3)(R)(R.sup.1)SiX的
硅烷化方法;其中,R是异丙基基团,R.sup.1是具有2到6个碳原子的单价碳氢基团,而X是
氯原子或
溴原子。本发明的
硅烷化试剂提供的
硅烷化产物比使用三
甲基氯硅烷得到的
硅烷化产物稳定得多,其保护基与使用叔丁基二
甲基氯硅烷得到的
硅烷化产物一样稳定。此外,本发明所描述的
硅烷化试剂的去
硅基化比叔丁基二甲基
硅基团更容易。
