The reaction of 1,1′-bis(2-chloroethoxy)ferrocene with 1,2-ethanedithiolate in absolute ethanol gave mononuclear 1,10-dioxa-4,7-dithia[10]ferrocenophane and binuclear 1,10,21,30-tetraoxa-4,7,24,27-tetrathia[10,10]ferrocenophane, along with a small amount of unexpected 1,13-dioxa-4,7,10-trithia[13]ferrocenophane and 1,16-dioxa-4,7,10,13-tetrathia[16]ferrocenophane. Extraction of aqueous metal picrates (M; alkali, alkaline earth, Ag+, Tl+, Cd2+, Co2+, Cu2+, Ni2+, and Hg2+) with dioxathia[n]ferrocenophanes was examined and also with the corresponding ring membered polyoxa[n]ferrocenophanes. Dioxathiaferrocenophanes showed a highly selective extraction ability towards bivalent mercury and copper ions.
