1,3,5-triaryl- 2-pyrazoline was irradiated with an ultraviolet light in ethanol under an oxygen atmosphere. The main products were 1.3, 5-triarylpyrazole (1.3, 5-triphenyl-2-pyrazoline to give 1.3, 5-tripheny - pyrazole in a 65% yield. 1,5-diphenyl- 3-(p-methylphenyl)-2-pyrazolioe to give1.5- diphenyl-3-(p-methylphenyl) - pyrazole in a 82% yield, 1,5-diphenyl - 3- (p-methoxyphenyl)-2 -pyrazoiine to give 1,5 – dipheny l- 3 - (p- methoxyphenyl)- pyrazole in a 65% yield and l,5- diphenyl - 3 - (p-chlorophenyl) -2-pyrazoline to give 1,5- diphenyl-3-(p- chlorophenyl )- pyrazole in a 56% yield). The reaction were followed by the determination of the disappearance of pyrazoline and that of the formation or pyrazole, Samo reactions of these compounds are described.
