Synthesis of Macrocyclic Bis(dithiocarbonic ester)s and Bis(thiocarbamate)s from Diethylene, Triethylene, and Tetraethylene Glycols

Article abstract of DOI:10.1246/bcsj.70.2515

The reaction of dipotassium bis(dithiocarbonate)s from diethylene, triethylene, and tetraethylene glycols with dibromoalkanes or ethereal oxygen-containing diiodides under high-dilution conditions gave 1:1 reaction products, 14-25-membered macrocyclic bis(dithiocarbonic ester)s. From dimethyl esters of the bis(dithiocarbonic acid)s and diamino-alkanes or ethereal oxygen-containing diamines, macrocyclic bis(thiocarbamate)s were obtained.
