摘要

Bis (8-Znaphthylethyl) disulfide (111), bis-p-(3, 4-dimethoxyphenyl) ethyl disulfide (VI), and bis (7-2-naphthylpropyl) disulfide (X) have been synthesized. In the presence of iodine, I11 undergoes ring closure, giving 2, 3-dihydronaphtho [l, 2-b] thiophene (IV). An excess of iodine converts I11 or IV into naphtho [l, 2-b] thiophene (V). Both 5, 6- dimethoxybenzothiophene (VIII) and 2, 3-dihydro-5, 6-dimethoxybenzothiophene (VII) are ...
