Aldehydes and ketones react with one equivalent each of thiols and thiolacetic acid under acid catalysis to yield almost exclusively the mixed alkylthio-(or arylthio-) acvlthioacetals. Reaction of the mixed thioacetal with a nucleoohile (such as NaOMe) liberates the thiolate anion which can be trapp
