ABSTRACT:
A process for preparing α-(3-arylthio)acetophenones of the general formula Iwhere the substituents R1and R2are each independently C1-C6-alkyl or an optionally substituted phenyl or benzyl radical, which comprisesA) reacting acetophenones of the general formula II where the substituent R1is as defined abovewith sulfuryl chloride and subsequently hydrolyzing, andB) reacting the reaction mixture obtained in this way with a thiophenol of the general formula III where the substituent R2is as defined above
