Abstract

Four benzopentathiepins (12, 14, 16, and 18) having a functional group, such as aminoethyl, pyridyl, pyrimidinyl, and thienyl groups, respectively, on the benzene ring were synthesized from 3-substituted 1,2-benzenedithiol by sulfurization with elemental sulfur in the presence of ammonia. These benzopentathiepins were characterized in the light of interaction of the pentathiepin ring with the functional group.
