摘要
合成了一种新型的纤维素负载的三苯膦(Cell-OPPh3),随后与醋酸钯反应生成了纤维素负载的三苯膦-钯复合物(Cell-OPPh3-Pd)催化剂,并对其进行了扫描电镜(SEM)、透射电镜(TEM)、热失重(TG)等分析表征。结果表明,催化剂对空气稳定,可有效催化空气条件下芳基卤和丙烯酸酯的Heck偶联反应。
A new cellulose supported triphenylphosphine (Cell-OPPh3) was synthesized and then coordina- ted with palladium acetate to form the catalyst cellulose supported triphenylphosphine-palladium(Cell-OPPh3- Pd). The catalyst was analyzed by SEM,TEM and TG. Catalyst Cell-OPPh3-Pd was stable and can catalyze the Heck coupling reaction of aryl halides with acrylates efficiently under air condition.
