A novel microwave-assisted method for the synthesis of 3-methyl-1- phenylchromeno[4,3-c]pyrazol-4(1H)-ones by the cyclization of 3-[1-(phenylhydrazono)ethyl]chromen-2-ones with CuO/SBA-15 under solvent-free conditions is described. The reaction gave the c
X-ray supramolecular structure, NMR spectroscopy and synthesis of 3-methyl-1-phenyl-1H-chromeno[4,3-c]pyrazol-4-ones formed by the unexpected cyclization of 3-[1-(phenylhydrazono)ethyl]-chromen-2-ones

The molecular structures of nine 3-methyl-1-phenyl-1H-chromeno[4,3-c] pyrazol-4-one isomers, obtained by the oxidative cyclization of the corresponding 1-phenylhydrazono chromen-2-ones with copper acetate as catalyst, are reported. The molecular and supra
