Abstract

Four novel N-aryl-2-thienyl substituted 1, 4-diazabutadiene (α-diimine) ligands 5–8 have been prepared by cyanide ion-catalyzed intermolecular coupling of the appropriate aromatic aldimines. A ligand featuring a phenyl spacer moiety between a thiophene carbon atom and each imino nitrogen atom (12) has been prepared by a similar synthetic route. Ligands 5–8 and 12 were characterized on the basis of 1H and 13C NMR, IR and MS-CI spectroscopy. ...
