چکیده
|
Different pyrazolone derivatives were prepared by microwave irradiation and ultrasound assisted methods besides the traditional ones. they were used for synthesis of some derivatives of spiropiperidine-4,4́-pyrano[2,3-c]pyrazole, dihydropyrano[2,3-c]pyrazole, pyrazole-4-carbothioamide, 4-(2-oxo-1,2-diphenylethylidene)-1h-pyrazol-5(4h)-one, azopyrazole, arylmethylenebis-1hpyrazol- 5-ol and araylidene-1h-pyrazol-5(4h)-one via reactions with different reagents applying the ultrasound method in some cases.
