different terminal olefins with various 3-iodo-benzopyrones including stericallyhindered, electron-rich, electron-neutral, and electron-deficient is developed. It proceeded faster and generally gave good to excellent yields under microwave irradiation, phosphine-free, and air condition. The reaction could render this method particularly attractive for the efficient preparation of biologically and

Abstract A series of 3,4-diaryl- 1H -pyrazoles derivatives were designed and synthesized by the reaction of 3-heteroarylchromones and 3-phenylchromones with hydrazine hydrate in good yields. All of those compounds were characterized by 1 H NMR, 13 C NMR, IR, and HRMS. Moreover, 3-(2,4-dihydroxyphenyl)-4-(4-hydroxyphenyl)- 1H -pyrazole and 3-(2,4-dihydroxy phenyl)-4-(4-methoxyphenyl)- 1H -pyrazole were
