PROBLEM TO BE SOLVED: To obtain the subject new compound as a specific S-difluoroalkenyl aromatic thio(dithio)carboxylic ester derivative, useful as an agricultural/ horticultural pest controlling agent. SOLUTION: This new compound is a compound of formula I (R is H, a halogen, or the like; X is O or S; Z is CH or N; (m) is 1-4; (n) is 3-8), e.g. S-(6,6- difluoro-5-hexenyl)thiobenzoic ester. The compound of formula I is obtained by reaction of an aromatic carboxylic acid chloride of formula II with a thiol compound of formula III in the molar ratio of the latter to the former of 0.5-2 in a solvent (e.g. benzene) in the presence of a base (e.g. triethylamine) pref. at room temperature to 50 deg.C for 0.5-5 h, wherein the amount of the solvent to be used is such that the compound of formula II accounts for pref. 10-70 wt.% of the whole reaction system, and the amount of the base to be used is pref. 1.0-1.5 molar times that of the compound of formula II.
