A simple and highly practical catalyst‐free O‐silylation of silanols with commercially available disilazanes has been developed under mild conditions. In the case of polyhedral oligomeric silsesquioxane (POSS) silanols and some other silanols, it was necessary to use catalytic amounts of inexpensive Bi(OTf)3 as additional catalyst. This efficient chlorine‐free protocol involves the synthesis of a wide
一个简单且高度实用的无催化剂Ø硅醇基与市售二硅氮烷-silylation已经温和的条件下开发的。对于多面体低聚倍半硅氧烷(POSS)硅烷醇和其他一些硅烷醇,必须使用催化量的廉价Bi(OTf)3作为附加催化剂。这种有效的无氯方案涉及多种重要有机硅衍生物的合成,例如不对称二硅氧烷和功能化的倍半硅氧烷。
