A kinetic study of the thermolysis of 4-crotyl-3,5-diphenyl-4H-1,2,4-triazole (1) in a melt of the neat compound was performed at temperatures in the range of 260–350 °C. The main products formed were 1-crotyl-3,5-diphenyl-1H-1,2,4-triazole (3) and 1-(1-methylallyl)-3,5-diphenyl-1H-1,2,4-triazole (4) together with 3-methyl-2,6-diphenylpyridine (2) and 3,5-diphenyl-1,2,4-triazole (5).
