Visible-Light-Enabled Preparation of Palladium Nanoparticles and Application as Catalysts for Suzuki–Miyaura Coupling

Silyl ketones were used for the preparation of palladium nanoparticles (PdNPs) starting with Pd­(OAc)2 in dimethylformamide under irradiation with a visible light-emitting diode (LED). Variation of the silyl ketone structure allowed adjustment of the PdNP diameter (1.9 or 5.2 nm). The in situ-formed...

Description
Summary:Silyl ketones were used for the preparation of palladium nanoparticles (PdNPs) starting with Pd­(OAc)2 in dimethylformamide under irradiation with a visible light-emitting diode (LED). Variation of the silyl ketone structure allowed adjustment of the PdNP diameter (1.9 or 5.2 nm). The in situ-formed PdNPs were further stabilized with polyvinylpyrrolidone and then applied as recyclable catalysts in the Suzuki–Miyaura coupling of arylboronic acids with aryl iodides to obtain substituted biphenyls in excellent yields.
