Abstract
The synthesis, spectral analysis and effect on some crop plants by some 4-Aroylpyrazolineswith 3- aroylflavone on treatment with phenylhydrazinehydrochloride in presence of peridine.We got two series while carried out in different aromatic acids. In series, we got 3-(2-hydroxy-3,5-dichlorophenyl)-4-anisoyl-5-(3-nitro phenyl) pyrazoline and 3-(2-hydroxy-3,5-dichlorophenyl)-4-benzoyl-5-(3’-nitrophenyl) 1-phenyl pyrazoline. It has been revealed that, the use of piperidine in DMSO as the solvent in the above reaction influences the rate of the reaction and also the yield of the products.. All these compounds have been analyzed by UV, IR and NMR for structure. The newly synthesized chlorosubstituted pyrazoline were studied.
