Palladium-catalyzed cross-coupling reactions between aryl (alkenyl) halides or triflates and organometallic reagents (Mg, Sn, B, Zn, Li, Zr, etc.) have been developed as a versatile and efficient method for a variety of synthetic transformations. 1., , , , , and Among these reactions, palladium-catalyzed cross-coupling reaction between aryl halides and aryl boronic acids, known as Suzuki–Miyaura reaction, is highly valuable for the synthesis of symmetrical and unsymmetrical biaryls. 2., ...
