Synthesis of Some New 3, 5-Bis (substituted) Pyrazoles and Isoxazoles Based on (N’1E, N’3E)- N’1, N’3-Bis (3, 4, 5-substitutedbenzlidene) Malonohydrazide under Solvothermal ConditionsKeywords: solvothermal , pyrazoles , isoxazoles Abstract: The new 3,5-(substituted) pyrazoles and isoxazoles were prepared by reaction of (N’1E, N’3E)- N’1, N’3-bis (3,4,5-substitutedbenzylidene)malonohydrazide with hydrazine hydrate and hydroxylamine hydrochloride respectively under solvothermal conditions involving an ecofriendly method without any environmental pollution, the yield are in the range of 75-96%. The structure of the new compounds were established using elemental analysis, IR, 1H NMR, 13C NMR.
