Abstract
Chemoselective trimethylsilylation and tetrahydropyranylation of benzylic and primary and secondary aliphatic alcohols proceed efficiently in the presence of 1,3-dibromo-5,5-dimethylhydantoin (DBH) under mild and completely heterogeneous reaction conditions in excellent yields.
Key words
alcohols - 1,3-dibromo-5,5-dimethylhydantoin - trimethylsilylation - tetrahydropyranylation - heterogeneous reaction conditions
