Abstract Using metal carbonyl fragments as templates, the directed, bridging alkylation of ligating dithiolates yields macrocyclic polythioethers. Treatment of cis-[Fe (CO) 2-(S 2 C 6 H 4) 2] 2−(1) with S (C 2 H 4 Br) 2, in THF at room temperature, gives [Fe (CO)-(dpttd)](2)(dpttd 2−= 2, 3, 11, 12-dibenzo-1, 4, 7, 10, 13-pentathiatridecane (2−)), which is alkylated by yet another S (C 2 H 4 Br) 2 under reflux to give dibenzo-18-crown-S6 (3) in 68% yield after ...
