Polyaniline-supported Sc, In, Pd, Os and Re catalysts were prepared by using a simple protocol and the thus prepared catalysts were well characterized using FTIR, XPS, UV-Vis/DRS, TGA-DTA. All the catalysts were successfully employed in a wide range of organic transformations such as cyanation and allylation of carbonyl compound, Suzuki coupling of aryl halides and boronic acids, and, most importantly
聚苯胺负载的Sc,In,Pd,Os和Re催化剂采用简单的操作流程制备,并使用FTIR,XPS,UV-Vis / DRS,TGA-DTA对如此制备的催化剂进行了很好的表征。所有催化剂均成功用于各种有机转化中,例如羰基化合物的氰化和烯丙基化,芳基卤化物和硼酸的Suzuki偶联,以及最重要的是,用于烯烃的不对称二羟基化以提供旋光的邻位二醇。通过简单的过滤将所有催化剂从反应混合物中分离出来,并以一致的活性重复使用五个循环,而没有明显的金属从载体中浸出。
