▎ 摘 要
The Pd17Se15 nanoparticles, synthesized for the first time from a single source precursor [Pd(L)Cl-2]{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%).
