Ruthenium(II) alkylidene complexes such as the Grubbs' 1st and 2nd generation catalysts undergo a ligand substitution with 2,2'-bipyridine, which readily leads to the common photoredox catalyst Ru(bpy)3 2+ . The application of this catalyst transformation in sequential olefin metathesis/photoredoxcatalysis is demonstrated by way of ring-closing metathesis (RCM)/photoredox ATRA reactions.
