摘要：
3-Formylchromones and 4-formylpyrazoles are treated with 3-methyl-1-(4-nitro phenyl) pyrazolin-5-(4H)-one in acetic acid under the influence of ultrasound wave to get title compounds 3-methyl-4-[(chromon-3-yl) methylene]-1-(4-nitro phenyl) pyrazolin-5-(4H)ones 1 and 3-methyl-4-[(1,3-diphenyl-1H-pyrazol-4-yl) methylene]-1-(4-nitro phenyl)pyrazolin 5(4H)-ones II respectively.
