摘要

Abstract Domino reactions for the synthesis of phenazines have been developed that start from 1, 2-diaminoarenes and 1, 2-dihaloarenes and proceed through palladium-catalyzed double N-arylations (inter-and intramolecular) followed by an in situ oxidation. A variety of functional groups, which include base-sensitive groups, were well tolerated under the optimized reaction conditions to afford phenazines in good to excellent yields. The ...
