Abstract: The reaction of chalcone with methylhydrazine produces a new compound, 1-methyl-3, 5-diphenyl-3-hydroxypyrazoline(Ⅲ).The unstable intermadiate can be dehydrated into pyrazoline. The dehydration process can be monitored by IRand UV, and is shown to be first order with respect to (Ⅲ).The absorption at 1680cm-1in compound (Ⅲ) is assigned to the structure
