ABSTRACT Thermolysis and/or microwave irradiation of thiosemicarbazones gave the corresponding isothiocyanates, which on addition of either activated nitriles or aldehydes furnished various types of azines. The mechanism was discussed. The structures of products were proved by MS, IR, NMR, and elemental analyses. GRAPHICAL ABSTRACT

allows the synthesis of azines with application in nonlinear optics, and the organic materials and biological active compounds crafting. oxMWNT catalysed the reaction in just 3 h with full recyclability upon the recovery of the catalyst. In addition, due to the inherent oxMWNT oxidative capacity in the presence of nitric acid, we have also developed the one-potsynthesis of azines starting from alcohols
