Improved process for producing 1,3-bis(2-pyridylimino)isoindolines and compositions containing transition metal complexes thereof. |
摘要 |
<p>There are disclosed an improved process for preparing a composition consisting essentially of at least one transition metal complex of a 1,3-bis(2-pyridylimino)isoindoline comprising contacting in a molten phase a 1,2-dicyanobenzene with at least one 2-aminopyridine in the presence of a transition metal complex and an improved process for preparing the 1,3-bis(2-pyridylimino)isoindoline ligand from the same starting materials comprising contacting in a molten phase said starting materials, optionally in the presence of an alkaline earth metal carbonate.</p> |
