Biaryl diamines are important building blocks in organic synthesis. Consequently, it is desirable to develop a general and mild synthetic approach to diverse biaryl diamines. Oxidative coupling is an efficient and promising strategy for the synthesis of these targets. We have now developed a direct formation of biaryl diamines by oxidative coupling using a hypervalent iodine(III) reagent.
