Abstract
The Pd17Se15 nanoparticles, synthesized for the first time from a single source precursor [Pd(L)Cl2] {L = 1,3-bis(phenylselenyl)propan-2-ol} and grafted onto graphene oxide, show high catalytic activity in C-O coupling between aryl/heteroaryl chlorides/bromides and phenol at room temperature (Pd loading 1 mol%; yield up to 94%).
摘要
首次由单源前体[Pd(L)Cl2]（L = 1,3-双（苯硒基）-2-丙醇）合成的 Pd17Se15 纳米粒子，并接枝到氧化石墨烯上，在室温下显示出芳基/杂芳基氯/溴化物与苯酚之间 C-O 偶联的高催化活性（Pd 负载量 1mol%；产率高达 94%）。
