Reactivity Of Tosylhydrazones Under Microwave Irradiata In Solvent-Free Environment

Abstract

The results of the interaction of microwave irradiation (multimode, 2.45 GHz, 100–600 W power) on tosylhydrazones, T.I., interesting intermediates in many organic reactions, were presented. T.I. were supported on silica, silica gel and alumina powders. Different inorganic salts (K₂CO₃ Fe(NO₃)₃ 9H₂O) were added to the reaction mixture. The results obtained, starting from a range of different T.I., were investigated by means of mass spectrometry and ¹HNMR in order to understand the role of microwave irradiation and presence of inorganic additives on the reaction pathway and yields.
