, p. 1939 - 1945 (2005)
Bronsted acidic ionic liquids as efficient and reusable catalysts for the protection of alcohols as tetrahydropyranyl (THP) ethers under solvent-free conditions at room temperature was investigated. Good to excellent yields were obtained at a faster rate over [BMIm][HSO4] or [BMIm][H2PO4]. Copyright Taylor & Francis, Inc.

Metal-free tetrahydrofuranylation of alcohols in the presence of tertbutyl nitrite is described, providing a facile and green route for the protection of hydroxy groups. Mechanistic studies demonstrate that this transformation proceeds in a radical way, and involves alkyl nitrite of corresponding alcohol as the key intermediate.
