Attempts at the oxidation of 3-ethyl-2-methylbenzothiazolium salt 2 with a variety of oxidizing reagents did not lead to the desired isochiral S-oxide 3 or achiral S,S-dioxide 4, in some cases, however, unexpectedly to the ring-opened dimeric 2,2′-di(N-ethyl-acetamino)substituted diphenyl disulfane 5, the molecular structure of which was confirmed by x-ray analysis. The synthesis of 2-methylbenzothiazole-S,S-dioxide 14, reported by Zincke et al. in 1915, turned out to be not reproducible.
