THE SYNTHESIS OF o-NITROBENZENETHIOLS: AN ADVANTAGEOUS NUCLEOPHILIC DISPLACEMENT ON o-CHLORONITROBENZENES
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.
