| Abstract: | A new method for synthesis of 3,5-diphenylpyrazole is reported. 1,3-diphenyl-2-propen-1-one is used as the starting material to get the intermediate of 2, 3-dichloro-1, 3-diphenyl-1-propanone,which will then react with excessive hydrazine hydrate to get 3,5-diphenylpyrazole. The results show that the new method is of many advantages, such as low reaction temperature, convenient operation and easily obtaining product with high purity etc. The final yield of the two steps reaction is as high as about 90%. Hydrazine hydrate can be recycled. |
