| Abstract: | 1-Phenyl-3-trifluoromethyl-2-pyrazolin-5-one 1 on heating with aromatic aldehydes at 160-70°C affords the corresponding 4- arylidene-2-pyrazolin-5-ones 3. while 3-amino-l-phenyl-2- pyrazolin-5-one 2 on heating with aldehydes gives pyrazolopyranopyrazole derivatives 4 with high yields. These new products have been characterized by spectroscopic techniques and elemental analysis. |
