In 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.

[PVP-SO3H] HSO4：一种高效的聚合固体酸催化剂，用于甲酰化和N-Boc保护反应

在目前的工作中，使用[PVP-SO ₃ H] HSO ₄作为无溶剂条件下的强固酸催化剂，对各种胺和醇进行了甲酰化反应。在这种催化条件下，胺的N- Boc保护也已在室温下成功完成。简便，经济的方法，反应时间短，产率高，化学选择性高，TOF高，后处理容易等优点是这项工作的优势。此外，[PVP-SO ₃ H] HSO ₄可以轻松分离并重复使用数次，而不会显着降低其催化活性。
