Abstract

The aryl-substituted N-picolylethylenediamine and diethylenetriamine ligands,( ArNHCH2CH2){(2-C5H4N) CH2} NH and (ArNHCH2CH2) 2NH (Ar= 2, 6-Me2C6H3, 2, 4, 6- Me3C6H2), have been prepared by employing palladium-catalysed N–C (aryl) coupling reactions of the corresponding primary amines with aryl bromide. Treatment of MCl2 with (ArNHCH2CH2){(2-C5H4N) CH2} NH affords [{(ArNHCH2CH2)((2-C5H4N) CH2) NH} ...
