nadium(IV) trifluoromethanesulfonate, [VIV(TPP)(OTf)2], in the trimethylsilylation of alcohols and phenols with hexamethydisilazane (HMDS) is reported. This new V(IV) catalyst was used as an efficient catalyst for silylation of not only primary alcohols but also sterically hindered secondary and tertiary alcohols with HMDS. Trimethylsilylation of phenols with HMDS was also performed to afford the desired
在目前的工作中,报告了缺电子的
四苯基卟啉钒(IV)
三氟甲磺酸盐[V IV(
TPP)(OTf)2 ]在醇和
酚与
六甲基二硅氮烷(
HMDS)的三甲基
硅烷化中的应用。这种新的V(IV)催化剂不仅用作伯醇与
HMDS的空间位阻仲和叔醇甲
硅烷基化的有效催化剂。还进行了
酚与
HMDS的三甲基甲
硅烷基化反应,得到了所需的三甲基甲
硅烷基醚(TMS)醚。还研究了该方法的
化学选择性。该催化剂可以重复使用几次而不会损失其活性。版权所有©2011 John Wiley&Sons,Ltd.
