Supported Sulfonic Acids: Solid Catalysts for Batch and Continuous-Flow Synthetic Processes

Abstract

It's easy being green! In this work, supported sulfonic acids were used as effective catalysts for different classes of reactions. They have the advantage of being cheap, safe, and easy to recycle. Reaction conditions are mild, have good atom economy, and work-up steps are very easy, satisfying essential parameters of the "green chemistry" philosophy. Application of these catalysts to continuous-flow processes resulted in a considerable improvement in efficiency.
