Participants

Reaction Steps

The compound 4-hydroxy-3,5-di-tert.-butyl dithiobenzoic acid was prepared by dissolving 2,6 -di-tert.-butyl phenol (20.6 g) in dimethylsulfoxide (60 cm3). To this well stirred solution under a nitrogen blanket was added KOH (5.6 g) dissolved in a minimum amount of water. After the addition was completed carbon disulfide (7.6 g) was added while maintaining the temperature between 20°-25° C. The mixture was maintained at this temperature for 1 hour, then at 60° C. for 2 hours, cooled and poured into water (250 cm.3). After acidification (10% HCl), extraction into diethyl ether and drying over Na2SO4 the product was isolated by rotoevaporation.
