Light-Induced Sonogashira CC Coupling under Mild Conditions Using Supported Palladium Nanoparticles
The Sonogashira reaction can easily be photocatalysed by supported palladium nanoparticles. We demonstrate that the direct excitation of the PdNPs can catalyze the C-C coupling between different aryl iodides and acetylenes under very mild conditions in short reaction times. The catalyst is air and moisture tolerant and can be supported in a wide range of materials, including inert ones such as nanodiamonds. Study of the action spectrum demonstrates that direct excitation of the PdNP isdoi:10.1021/acssuschemeng.7b02992.s001 fatcat:kh7u3lb23rhwdpobxtu3logu3q
