Abstract

The interaction of lanthanide shift reagents (LSR) with pyridine analogs of isoflavone and their derivatives has been studied. It was found that the pyridine nitrogen atom can increase the coordinating ability of electron donor groups in the molecule, in particular the sulfur atom in chromone thiones. It has been shown that LSR interact actively with pyridinium methylsulfate salts containing the 3-chromone substituent. The efficiency of the coordination is influenced by the occurrence of steric hindrance around the chromone carbonyl. The structure of the adducts of these salts with LSR is discussed.
