Reaction of dithioic acids with dicyclohexylcarbodiimide has been found to give the corresponding bis(thioacyl) sulfides 1 in good yield, which are very useful thioacylating reagents under mild reaction conditions. Most of the aromatic thioanhydrides ( 1 , R = aromatic) are fairly stable green crystals at room temperature, but the aliphatic ones ( 1 , R = aliphatic) are unstable purple oils which dimerize at room temperature to give the dithietanes 5 . The reactions with nucleophiles are discussed.
