Heterogeneous photocatalytic C–C coupling- mechanism of plasmon-mediated reductive dimerization of benzyl bromides by supported gold nanoparticle

The use of gold nanoparticles supported on TiO2 (Au@TiO2) as photocatalysts was extended to include photoinduced reductive C–C coupling. Surface plasmon excitation of supported AuNPs in the presence of an amine leads to the C–C coupling of a variety of substituted benzyl bromides at room temperature with good yields in a free radical-mediated reaction. The overall efficiency of the C–C coupling is largely dependent on the nature of the amine used.
