Abstract

The scope of heterogeneous catalytic organic transformations is rapidly growing due to their well-documented advantages over homogeneous catalytic systems. Clays have emerged as ideal acidic heterogeneous catalysts as they are available in nature and are thus inexpensive. These clays have Brønsted as well as Lewis acidic sites 1 and thus increase their utility in both types of catalytic applications. The positive features of clays also include ...
