Iodine-Catalyzed Mild and Efficient Tetrahydropyranylation / Depyranylation of Alcohols

Alcohols and phenols are tetrahydropyranylated rapidly in high yields in the presence of catalytic amount of iodine at room temperature. Depyranylation is effected readily by refluxing with iodine in methanol for few hours.
