Boosting photocatalytic Suzuki coupling reaction over Pd nano-particles by regulating Pd/MOF interfacial electron transfer
文献摘要：
Palladium-catalyzed C-C coupling reactions are of significant importance,but they often require harsh condi-tions.Herein,we report an interface-regulated photocatalytic Suzuki coupling reaction over Pd nanoparticles supported on a metal-organic framework(MOF),ZIF-8.Two Pd/MOFs were synthesized,PdPVP/ZIF-8 and Pd/ZIF-8,which have simil-ar Pd sizes and loading amounts,except that the former contains poly(vinylpyrrolidone)(PVP)as a surfactant.The diffuse-reflectance infrared Fourier transform of CO adsorption(CO-DRIFT)indicates that Pd/ZIF-8 represents a more negative electronic state of Pd than PdPVP/ZIF-8.In the photocatalytic Suzuki coupling reaction between iodobenzene and phenyl-boronic acid,Pd/ZIF-8 exhibits excellent performance(99.1％yield),much better than that of PdPVP/ZIF-8(57.9％yield).Moreover,Pd/ZIF-8 is highly stable and shows broad substrate scope for this reaction.The superior activity of Pd/ZIF-8 can be attributed to sufficient electron transfer between the MOFs and Pd nanoparticles in the absence of an interfacial sur-factant.This work provides new insights into a Pd-catalyzed C-C coupling reaction involving photocatalysis and interfa-cial electron transfer.
