| Abstract: | Abstract Tetrahydropyranylation of alcohols and phenols was accomplished successfully using copper nitrate and acetic acid as a synergistic
catalyst at room temperature under solvent-free condition. Compared with other synergistic catalytic systems, copper nitrate/acetic
acid proved to be the most efficient. Both alcohols (primary, secondary, tertiary, benzylic, cyclic, allyl, cinnamyl, and
furyl) and phenols reacted smoothly in high yields.
