DUAL CATALYSIS

Golden potential

Due to the high oxidation potential of gold, the development of dual gold/photoredox-catalysed processes has been limited by the need for an easily reduced radical source. Now, discovery of an energy transfer photoexcitation process overcomes this limitation, enabling the oxidative addition of iodoalkynes onto organogold intermediates.
