PVP-SO3H HSO4: An Efficient Polymeric Solid Acid Catalyst for the Formylation and N-Boc Protection Reactions

摘要

abstract_textpIn the present work, the formylation of a variety of amines and alcohols was performed using PVP-SO3H HSO4 as a powerful solid acid catalyst under solvent-free conditions. Under this catalytic condition, N-Boc protection of amines was also successfully done at room temperature. Easy and economical methodology, short reaction times, high yields, chemo-selectivity, high TOF and easy workup are some of the advantages of this work. Furthermore, PVP-SO3HHSO4 can be easily separated and reused for several times without considerable loss of its catalytic activity./p/abstract_text
