Localized surface plasmon resonance assisted photoredox catalysis using newly fabricated copper-nanorods: a decarboxylative approach towards carbon-hydrogen bond formation under visible light

The plasmonic behaviour of synthesized copper nanorods (Cu-NRs) plays an important role in redox processes as well as in coupling. A benign decarboxylative approach is developed to produce alkane analogues from corresponding alkyl carboxylic acids using these Cu-NRs via localised surface plasmon resonance (LSPR) assisted catalysis under visible light. A broad substrate scope and functional group tolerance are observed without any external oxidant or proton source. A plausible mechanism has also been proposed for this recyclable nano-catalyst based on some control experiments. Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior, serving as efficient catalysts in an environmentally friendly decarboxylative process that converts alkyl carboxylic acids to alkane analogues under visible light.
