Chemoselective trimethylsilylation of alcohols catalyzed by saccharin sulfonic acid
摘要:
Saccharin sulfonic acid was easily prepared by the reaction of saccharin with neat chlorosulfonic acid at room temperature. This reagent is efficiently able to catalyze the chemoselective trimethylsilylation of alcohols with hexamethyldisilazane in the presence of amines and thiols.
