hexamethyldisilazane (HMDS) for the efficient and selective silylation of alcohols. Primary, secondary, and tertiary alcohols and phenols are efficiently converted to their corresponding silylethers in short reaction times (4–8 min) with excellent yield at rt under solvent-free condition. Simple and clean reactions, high yield of the products and efficient recycling of the catalyst are the salient features of
Nafion SAC-13可有效活化六甲基二硅氮烷(HMDS),以实现酒精的高效选择性硅烷化。伯,仲和叔醇和苯酚在较短的反应时间(4-8分钟)内可在无溶剂条件下在室温下高效转化为相应的甲硅烷基醚,并具有出色的收率。简单干净的反应,产物的高收率和催化剂的有效循环是该方法的主要特点。
