Chemoselective and Regiospecific Suzuki Coupling on a Multisubstituted sp3-Carbon in 1,1-Diborylalkanes at Room Temperature

The palladium-catalyzed Suzuki-Miyaura cross-coupling on a multisubstituted sp(3)-carbon in 1,1-diborylalkanes was achieved at room temperature. The generation of a monoborate intermediate by virtue of the adjacent B atom could result in the chemoselective coupling reaction under ambient conditions.
