Several 2-alkoxycarbonyltrifluoromethanesulfonanilides were prepared to examine their miticidal activity. 4-Halo-2-alkoxycarbonyltrifluoromethanesulfonanilides in particular showed good miticidal activity against Tyrophagus putrescentiae (Tp), Dermatophagoides farinae (Dp) and Chelacaropsis moorei (Cm). Amidoflumet (methyl 5-chloro-2-[(trifluoromethyl)sulfonyl]aminobenzoate) was selected and has been developed as a new miticide for house dust mites.

and amino proton. This interaction also increased the nucleophilicity of the amino group. Thus, in the presence of 20 mol % of 2-(trifluoromethanesulfonamido)benzoic acid, intramolecular hydroamination of unfunctionalizedolefins gave the corresponding products in up to 95% isolated yields.
