Abstract

The synthesis of a new bifunctional ligand 1-(p-carboxybenzyl)-N, N′-bis-[1, 1-dimethyl-1- (p-methoxybenzylthio) ethyl]-ethylenediamine-N, N′-diacetic acid, di-t-butyl ester (1, nbi6ss) is described. It consists of a carboxybenzyl group substituted on a carbon atom of the ethylenediamine moiety of a hexadentate ligand, which has been found to have a very high affinity for In (III). The gem-dimethylthiol groups and the carboxylic acid groups of the ...
