摘要：
An efficient method for sterically demanding Suzuki-Miyaura coupling reactions has been developed with two catalysts, Pd/BI-DIME (see scheme) and Pd/phenanthrene-based ligand. The Pd/BI-DIME catalyst facilitates the syntheses of extremely hindered biaryls bearing ortho-isopropyl substituents. The other catalyst is efficient for the synthesis of functionalized tetra-ortho- substituted biaryls at low catalyst loadings. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
