The direct hydroamination of alkynes driven by visible light can be achieved in high yield and selectivity at ambient temperature using supported gold nanoparticles (AuNPs) as photocatalysts. Aniline molecules interact with visible light activated AuNPs meanwhile alkynes could be activated at active sites on the support. The findings reveal a new green approach for synthesis of fine organic compounds and provide insight into catalyst design for the activation of CC triple bonds and amines.
