Abstract:

Alkyl 2 center dot mercaptophenyl ketones react with trifluoroacetic anhydride the presence of triethylamine to give 2-(trifluomethyl)center dot 4ll-thiochromen-4-ones, which are transformed. into the corresponding pyrazoles by treatment with hydrazine hydrate and into 1, 1 -dioxides by oxidation with H2O2 in AcOH.
