A kinetic study of the thermolysis of n-crotyl substituted 1,2,4-triazoles

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-dipheny1-1H-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). Products 2 and 5 were both formed preferentially from 3 and 4. In the melt was observed first order kinetics. Activation parameters for formation of 3 and 4 were determined. Product 3: E(a) = 95 kJ/mole. Product 4: E(a) = 145 kJ/mole.
