An efficient and green novel microwave assisted organic synthesis (MAOS) method has been developed for dinitro cinnoline derivatives with better yields. The framework of these derivatives was constructed from dinitrophenyl arylethylidene hydrazines. Tetrabutylammonium bromide (TBAB) was used as a phase transfer catalyst (PTC), potassium carbonate as an inexpensive and efficient catalyst and water as solvent due to its polarity which helps to increase the temperature substantially. This methodology features a simple, environmentally friendly approach, employing water as a green solvent and using a one-pot reaction. The use of microwave increases the rate of reaction and it was observed that dinitro arylcinnolines can be synthesised in 8-12 min of microwave irradiation compared to conventional thermal heating protocol which requires more than 2 h. Spectral data confirms the identity of synthesized derivatives and satisfactory yields are obtained by this process
