    • (a) Compounds of the family Ar-BIAN (Ar-BIAN = bis(aryl)-acenaphthenequinonediimine) have been known for some time but have been brought to general attention only in recent years by Elsevier and his group. Since then, they have found widespread use as ligands for palladium, ruthenium, and nickel and the corresponding complexes have been employed as catalysts for a wide variety of reactions. For a list of applications see ref 5 and references therein.

    • (a) Another Lewis acid scale reported by the same authors and based on EPR data suffers from the same limitations as that based on fluorescence data but also requires a sophisticated apparatus and is of more limited application.

    • note
    • Moreover, it is expected that the sensitivity of the equilibrium constant to a substituent on the ring of a pyridine ring should be much higher than that observed for the AR-BIAN ligands, in which the aryl group lies more or less perpendicularly to the -N=CC=N- moiety. Since the sensitivity displayed by Ar-BIAN ligands is already such that in several cases the coordinating strength of the more electron-poor ligands could not be determined, the measurement of accurate equilibrium constants with different phenanthrolines or bipyridines would probably be confined to a limited range of substituents having σ constants close to each other. This would strongly affect the reliability of the correlation in a negative way.
