Tetrahydrofuranylation of alcohols catalyzed by alkylperoxy-λ3-iodane and carbon tetrachloride

Reaction of primary and secondary alcohols with tetrahydrofuran and a catalytic amount of 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one in the presence of carbon tetrachloride at 50 °C provides an efficient method for protecting the hydroxy group as 2-tetrahydrofuranyl ethers.
