ABSTRACT:
A process for production of an alkylthiobenzoate comprising reacting a cyclohexenone having the formula ##STR1## in which R.sub.1 is C.sub.1 -C.sub.6 alkyl; X is alkyl or unsubstituted alkyl; and Y is hydrogen, halogen or alkyl, with a mercaptan having the formula R.sub.2 SH in which R.sub.2 is C.sub.1 -C.sub.4 alkyl, preferably in the presence of an acid catalyst, to form a cyclohexadiene thioether, and dehydrogenating the thioether to produce a thioalkylbenzoate.
The thioalkylbenzoate may be further converted by oxidation and/or hydrolysis to a corresponding thioalkyl, alkylsulfinyl or alkylsulfonyl benzoic acid.
