Alkyl- and aryl-acyl derivatives of geminal dithiols

Alkyl- and Aryl-acyl Derivatives of Geminal Dithiols The reaction of α-halosulfides 3 with alkali salts of thiocarboxylic acids 4 or α-haloalkyl-acyl sulfides 7 with alkyl and aryl mercaptans 6 yields alkyl- or aryl-acyl derivatives of methane-, ethane- and propane-1,1-dithiol 5 .
