Description:
Microwave-expedited solvent-free synthetic processes will be described for the synthesis of a variety of industrially significant compounds and intermediates namely, enamines, nitroalkenes, enones, oxidized sulfur compounds and ionic liquids. This solvent-free synthetic methodology involves microwave exposure of reactants in neat form or their reaction in presence of a catalyst or catalyzed by the surfaces of inexpensive and recyclable mineral oxides namely silica, alumina, clay, or 'doped' surfaces. The salient features of these high yield protocols, namely the enhanced reaction rates, greater selectivity and the experimental ease of manipulation will he highlighted.
