nucleophilic substitution for the nitrogroup in E-2,4,6-trinitrostilbenes under the action of arene- and alkanethiols or phenols in the presence of inorganic bases was studied. Products of o-NO2 groupreplacement in the presence of PhCH2SH were used to obtain earlier unknown 2-aryl-4,6-dinitrobenzo[b]thiophenes and their 3-chloro derivatives. In these fused heterocycles, the 4-NO2 group can be selectively displaced

A method for the synthesis of previously unknown 2-aryl-4,6-dinitrobenzo[b]thiophenes and their 3-chloro derivatives has been developed based on the replacement of ortho-NO2 in (E)-2,4,6-trinitrostilbenes on treatment with PhCH2SH/K2CO3 followed by transformations of the resulting 2-benzylthio-4,6-dinitrostilbenes by treatment with SO2Cl2.
