METALLOCENE BIS(AZA-CROWN ETHER) LIGANDS AND RELATED-COMPOUNDS - THEIR SYNTHESES, COORDINATION CHEMISTRY, AND ELECTROCHEMICAL PROPERTIES

Abstract:

The syntheses of new ferrocene and ruthenocene bis(aza-crown ethers) (11)-(14) containing amide bond linkages between the metallocene redox centre and aza-15-crown-5 (1,4,7,10-tetraoxa-13-azacyclopentadecane) and aza-18-crown-6 (1,4,7,10,13-pentaoxa-16-azacyclo-octadecane) are described. Variable-temperature 13C n.m.r. studies on these compounds reveal a common intramolecular dynamic process involving rotation about the N-CO bond whose energy barrier to rotation is cation (Na+ or Li+) depende...
