Synthesis and Properties of Coronands Incorporating Lariat Sulfide and Sulfoxide Groups

Abstract

A series of 8-substituted 19-methoxy-17-methyl-3,6,10,13- tetraoxabicyclo[13.3.1]nonodeca-1(19),15,17-trienes has been prepared and their complexations with alkali metal and ammonium cations studied. When the 8-substituent contained sulfide functionality weak complexes formed, but hosts with lariat sulfoxide substituents formed complexes- with greatest specificity for lithium ions.
