Synthesis of Imidazole-Based Functionalized Mesoionic Carbene Complexes of Palladium: Comparison of Donor Properties and Catalytic Activity toward Suzuki–Miyaura Coupling
corresponding mesoioniccarbene complexes with palladium were prepared via oxidative addition without protection of the C2 position. The donor properties were evaluated with 31P NMR spectroscopy of the respective palladium complexes. The catalytic activity of these complexes toward Suzuki–Miyaura coupling of aryl bromides was also explored. Also, in one case, a comparison of donor properties was made with
已使用金属-卤素交换程序合成了三种不同的骨架单官能化咪唑鎓盐,并且通过氧化加成在不保护C2位置的情况下制备了它们与钯的相应的中离子卡宾配合物。用相应的钯配合物的31 P NMR光谱法评价了供体性质。还研究了这些配合物对芳基溴化物的Suzuki-Miyaura偶联的催化活性。同样,在一种情况下,将供体性质与具有类似空间体积的“正常”卡宾的供体性质进行了比较。
