Chavez, Flavio published the artcileSulfuric acid adsorbed on silica gel. An efficient catalyst for the tetrahydropyranylation of alcohols, Formula: C10H16O2, the publication is Synthetic Communications (1992), 22(1), 159-64, database is CAplus.
Sulfuric acid adsorbed on silica gel is an efficient catalyst for the tetrahydropyranylation of alcs. and phenols. The reaction takes 1 to 10 min to be completed and nearly quant. yields are obtained. The method is remarkably simple and inexpensive.
