Claims6
Process for the production of 2,2′-dithiazolyl disulfides of the general formula
- 5
- wherein
- R and R1 can be the same or different and each denote hydrogen, halogen, nitro, hydroxyl or optionally substituted C1-C12 alkyl or alkoxyl or C6-C12 cycloalkyl or aryl or C1-C12 heteroaryl, or jointly form the residue
- 6
- wherein
