Abstract : The acid catalyzed ring-closure of disulfide to form thiophene or hydrox-thiophene rings was extended to include larger rings such as the thiachroman ring. It was shown that ring-closure occurs readily in o-biphenylyl disulfide to form dibenzothiophene in beta-2-naphthylethyl disulfide to form naphtho (1,2-b) dihydrothiophene, and in alpha-2-naphthylpropyl disulfide to form 7,8-benzothiochroman. In addition, some unusual examples of cyclization of open-chain disulfides were discovered, and preliminary steps to develop conditions for inter-molecular electrophylic substitution by disulfides were made.
