Transition metal-catalyzed cross-coupling procedures have revolutionized the art and practice of organic synthesis in industry and academia. 1 The very mild reaction conditions and broad availability of diverse reaction partners underpin the versatility of the Stille, 2 Suzuki−Miyaura, 3 and Hiyama 4 cross-coupling protocols, in particular. In these important processes, organostannanes, boronic acids, and silanols are most often paired with ...
