Thermolysis of triazoles as melts - Is the 3,5-diphenyl-1,2,4-triazole group a good leaving group?

The mechanism of the rearrangement of 4-alkyltriazoles to the corresponding 1-alkyltriazoles on thermolysis at 330 °C is shown to involve initial formation of an intermediate 1,4-dialkyltriazolium triazolate salt. The triazolate ion subsequently attacks at the alkyl group bearing 1- and 4-positions of the dialkyltriazolium ion, yielding the observed products. No evidence for unimolecular reaction steps has been found. The triazole moiety in these compounds is only a weak leaving group, which requires activation by alkylation. Unimolecular reaction steps never take place, neither from neutral triazole species nor from activated dialkyl-substituted triazolium species.
Thermal rearrangement of 4-alkyl-4H-1,2,4-triazoles to 1-alkyl-1H-1,2,4-triazoles - A study of the mechanism by cross-over experiments

The mechanism for the thermal rearrangement of 4-alkyl-1,2,4-triazoles to the corresponding 1-alkyl-1,2,4-triazoles, was studied by cross-over experiments with mixtures of 4-ethyl-3,5-diphenyl-4H-1,2,4-triazole and 3,5-bis(4-methylphenyl)-4-propyl-4H-1,2,
