Abstract
The nucleophilic substitution of substitutedo-nitrochlorobenzenes with substituted methanethiolates, catalysed with triethylamine or pyridine, has been used to
prepare a series of appropriately substituted methyl-o-nitrophenylsulfides. The prepared compounds were identified by their1H- and13C-NMR spectra. The base catalysed ring closure of methyl 2-(methoxycarbonylmethylsulfanyl)-3,5-dinitrobenzenecarboxylate
only results in an attack of carbanion on the ester group, not on a nitro group as with the other compounds prepared.
