| Research Abstract |
We synthesized polyesters via dehydration polycondensation of 3, 3'-dithiodipropioicacid with diols and a, wdihydroxyl polymers including polycaprolactonediol(Mn=1. 6X 103, MW/Mn=1. 8) using scandium catalysts(0. 5 mol%). Subsequently, we performed cleavage of the disulfide linkage to give expected dithiol in good yields. The conversions of the functional group were confirmed by II-1 NMR and MALDI-ToF spectra. We also performed the conversion of 1, 2bis(2azideethoxy) ethane for the corresponding dithiol via "click" polymerization(yield 94%).
