Trifluoromethyl substitution on the pyrazole ring was found to enhance photoreactivity via the P 4 pathway which involves interchange of the N2-C3 ring atoms. Thus, 1-methyl-3-(trifluoromethyl)pyrazole (1) and 1methyl-5-(trifluoromethyl)pyrazole (3) transposed with a P 4 /P 6 or P 4 /P 6 +P 7 ratio
## Abstract The major products from the reaction of Ξ²βalkoxyvinyl trifluoromethyl ketones **1aβc** with methylhydrazine (**2**) in absolute ethanol are the 3β(trifluoromethyl)βsubstitutedβ1βmethylpyrazoles **3aβ3c** with lesser amounts of the 5β(trifluoromethyl)βsubstituted products **4aβ4c** and *
