Synthesis, crystal structure, characterization and antifungal activity of 3,4-diaryl-1H-Pyrazoles derivatives

Fourteen 3,4-diaryl-1H-pyrazoles (4 and 5) derivatives were designed and synthesized by the reaction of chromone with hydrazine hydrate in good yields. The synthesized compounds were characterized by the method of 1H NMR, 13C NMR, IR and HRMS and were evaluated their antifungal properties against five phytopathogenic fungi.168
