Abstract
The leading contenders for environmentally acceptable processes are supported reagents. [19] Since the activity and selectivity of a reagent dispersed on the surface of a support is improved as the effective surface area of the reagent can be increased manifold, the reaction is expected to be complete in short reaction times. Good thermal and mechanical stabilities, ease of handling due to invariably low toxicity and non-corrosive free flowing nature, ease of separation ...
