been carried out on 3(5)-trifluoromethyl-5(3)-methylpyrazole and 3,5-bis(trifluoromethyl)pyrazole. In both cases, the reaction proceeds with elimination of nitrogen and the formation of complex mixtures of fluorinated olefins and acetylenes. The Arrhenius parameters have been determined and discussed. The first step of the reaction, a pyrazole/pyrazolenine tautomerization process, has been calculated
