An efficient one-pot method for the preparation of 2-nitro-4- (trifluoromethyl)benzene containing sulfides from 1,1'-disulfanediylbis[2-nitro- 4-(trifluoromethyl)benzene] is proposed. The corresponding enantiomerically enriched sulfoxides with up to 78% enantiomeric excess are prepared by the asymmetric oxidation of sulfides using a modified Sharpless method. The yield of sulfoxides is shown to decrease with an increase in the bulk of the aliphatic group and with a decrease of the inductive effect of the hydrocarbonic moiety on the sulfur atom.

Reaction of substituted o-chloronitrobenzenes with sodium sulphide in DMSO occurs rapidly and gives the corresponding o-nitrobenzenethiols, following a convenient one-step pathway.Better yields are obtained when stoicheiometric amounts of sulphur, dissolved in a little carbon disulphide, are added in the presence of ethyl methyl ketone as solvent.
