Pyridinium alkane-and arenethiolsulfonates were allowed to react with arenesulfenyl chlorides, CISAr′, to yield sulfonyl disulfides in which R is n-dodecyl, benzyl, phenyl, or p- tolyl group, and Ar′ o-nitrophenyl or o-nitro-p-chlorophenyl. p-Toluenesulfonyl p- nitrophenyl disulfide was also prepared by this method. IR and UV spectra of these compounds were determined and compared with those of the corresponding ...
