Abstract
Decarboxylative thioesterification of isatoic anhydrides mediated by benzyl(triethyl)ammonium tetrathiomolybdate gave the corresponding S-alkyl or S-aryl 2-aminobenzenecarbothioate derivatives at 60 degrees C. At ambient temperature, organic disulfides were reductive cleaved in the presence of tetrathiomolybdate to generate thiolate anions in situ; this was followed by attack on isatoic anhydrides to give the corresponding S-alkyl or S-aryl 2-aminobenzenecarbothioate derivatives. Additionally, it was shown that multistep reactions could be performed with tetrathiomolybdate, starting with an alkyl halide as a precursor of an alkyl disulfide, which, in turn, was used for ring opening of isatoic anhydrides.
