摘要
Six novel 4,4'-bipyridine-crown-esters, derived from [4,4']bipyridinyl-3,3'-dicarboxylic acid, [4,4']bipyridinyl-2,2'-dicarboxylic acid and [4,4']bipyridinyl-2,2',6,6'-tetra-carboxylic acid were synthesized employing a procedure closely related to the 'cesium carbonate method'. The 4,4'-bipyridine-crown-esters differ in their substitution positions of the aromatic bipyridine-units, as well as in the geometric extensions of their crown-ester moieties. Addition of 1,3-propane sultone to the 4,4'-bipyridine-crown-esters resulted in five novel propanesultonated 4,4'-bipyridine-crown-esteiviologens.
