Solvent free tetrahydropyranylation of phenols and alcohols over zeolites HSZ as reusable catalysts
摘要:
Phenols and alcohols are tetrahydropyranylated in the presence of zeolites HSZ in good to excellent yields and selectivities. Addition of methanol performs the complete deprotection. (C) 1997 Elsevier Science Ltd.
