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
已经开发出了一种有效的空间要求苛刻的Suzuki-Miyaura偶联反应的方法,该方法使用两种催化剂,Pd / BI-DIME(参见方案)和Pd /菲基配体。Pd / BI-DIME催化剂促进了带有邻-异丙基取代基的受阻极强的芳基化合物的合成。另一种催化剂可在低催化剂负载下有效合成官能化的四邻位取代联芳基。
