These salts are precursors for a new class of N-heterocycliccarbeneligands. As a consequence of their bicyclic geometry, these ligands are capable of influencing the coordination sphere of a carbene bound metal. The usefulness of these ligands was demonstrated in the palladium-catalyzed Suzuki–Miyaura cross-coupling of stericallyhinderedarylchlorides.
据报道,已经合成了不同取代的2 H-咪唑并[1,5 - a ]吡啶-4-溴化铵。这些盐是新型N-杂环卡宾配体的前体。由于其双环几何结构,这些配体能够影响卡宾键合金属的配位球。在钯催化的空间受阻芳基氯的Suzuki-Miyaura交叉偶联中证明了这些配体的有用性。
