Abstract
AbstractIn 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‐SO3H]HSO4 can be easily separated and reused for several times without considerable loss of its catalytic activity.
