Abstract:
A study was made of the preparation and properties of unsymmetrical disulfide , and related S compounds, with sp cial emphasis on their spectral properties. Initial studies on mixed aryl alkyl disulfides showed that in the liquid state these substances underwent equilibration Ultraviolet spectral studies on examples where the unsymmetrical disulfide could be isolated and well characteri ed showed that curves for the pure symmetrical disulfides, and no shifts occurred during the equilibration r action. Preli inary work on the Arbuzov reactio with symmetrical disulfides indicated that some light could be shed on the cleavage of unsymmetrical disulfides by the isolation of products of their reaction with triethyl phosphite. Studies on the synthesis of unsymmetrical alpha-disulfones showed that previous syntheses described in the literature for symmetrical alpha-disulfones could not be applied to unsymmetrical cases, since mixtures of symmetrical and unsymmetrical products wer again obtained. The acid-catalyzed ring-closure of disulfid s to form thiophene or hydrothiophene rings ha been studied. The syntheses and UV spectra of pure trans-pmercaptocinna ic acid, not previously reported, p-mercaptobenzoic acid, and suitable derivativ s of th se compounds, including the disulfides, were achieved.
