Abstract

(E)-3-(2-chlorophenyl)- 1-(2,4-dichlorophenyl) prop-2-en-1-one was prepared from 2-chlorobenzalde-hyde followed by cyclization with hydrazine monohy-drate. Eight new 3-(2,4-Di-chlorophenyl)-5-(2-chlorophenyl)-4,5- dihydro-N-acylpyrazole derivatives were synthesized and characterized by elemental analysis, IR and 1H NMR spectroscopy. The experimental results show that the inhibition ratio of compounds 3f towards H. Oryzae and P. Oryzae at 50 mg.L-1 is 55.2% and 57.1%, respectively. The inhibition ratio of compounds 3g towards H. Oryzae, P. Oryza, S. Sclerotiorum at 50 mg·L-1 is 53.3%, 60.0%, 50.4% respectively.
