ABSTRACT:
A process for the preparation of a pyridinyl-linked bis-amino ligand that comprises, (a) reacting 2,6-dibromophenyl amine with an arylboronic acid component which is substituted or unsubstituted to produce a 2,6-diarylphenyl amine which is substituted or unsubstituted; (b) reacting the 2,6-diarylphenyl amine with a 2,6-dialkanoic pyridine characterized by the formula:wherein R′ and R″ are each independently a C1–C20hydrocarbyl group; to produce a mono-imine ligand characterized by the formula:wherein TRP is a terphenyl group which is substituted or unsubstituted; and (c) reacting the mono-imine ligand with an aniline which may be substituted or unsubstituted to produce a bis-amine ligand characterized by the structure:wherein: TRP is a substituted or unsubstituted terphenyl group; and AR is a substituted or unsubstituted aryl group.
