Notes: 2,4-O-Benzylidene-1,6-dithiol-D-glucitol is prepared by nucleophilic displacement of tosyloxy groups from 3,5-di-O-acetyl-2,4-O-benzylidene-1,6-di-O-tosyl-D-glucitol with thioacetate in N,N-dimethylformamide and deacetylation of the product. Oxidative polymerization with oxygen and selenium dioxide produces film-forming disulfide polymers with intrinsic viscosities up to 0.41. Other oxidizing agents produce polymers of lower viscosity. Condensation of the dithiol with benzaldehyde also gives polymers of low viscosity.
