Straightforward Synthesis of Substituted p ‐Quinones: Isolation of a Key Intermediate and Use as a Bridging Ligand in a Diruthenium Complex

Keep it simple: A new transamination method is reported for the synthesis of diamino-substituted p-quinones (see scheme). Asymmetrically substituted p-quinones are shown to be key intermediates in this reaction. The redox properties of these ligands are discussed and their utility in coordination and redox chemistry is shown with a representative example.
