New macrocyclic bis-1,10-phenanthroline-2,9-diamides. synthesis and stereodynamics in solutions

Abstract

New examples of macrocyclic 1,10-phenanthroline-2,9-diamides containing simultaneously two phenanthroline moiety in their structure have been obtained. The structure of the obtained compounds was confirmed by NMR spectroscopy and other methods. New macrocyclic phenanthrolines expectedly exhibit complex stereodynamic behavior in solutions. This effect was studied using 1H NMR spectroscopy at various temperatures.
