MCM-41-anchored sulfonic acid (MCM-41-SO3H): An efficient heterogeneous catalyst for green organic synthesis

MCM-41-anchored sulfonic acid (MCM-41-SO₃H) used as a solid acid catalyst has been reported in recent years for various synthetic protocols. The superior advantage of MCM-41-SO₃H is that it can be recovered and reused several times without loss of its efficiency. In this tutorial review, we attempt to give an overview of the use of MCM-41-SO₃H as a solid and heterogeneous catalyst in the synthesis of various organic compounds that have industrial and pharmaceutical applications.
