摘要：

Hydrolysis of the zwitterionic adducts formed from Bu3P, CS2 and norbornene or norbomadiene gives Bu3PO and the corresponding norbornane-fused 1,3-dithiolanes. Oxidation of these gives endo-sulfoxides while attempted hydrolysis using HgCl2 and CdCO3 instead leads to formation of crystalline 1:1 HgCl2 adducts. Based on this observation, a range of robust and readily accessible polymers containing norbornane-fused dithiolane units are evaluated for absorption of HgCl2 from aqueous solution.
