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/photoredox catalysis is demonstrated by way of ring-closing metathesis (RCM)/photoredox ATRA reactions.

RuII-烷叉基取代Ru（bpy）3 2+的配体：顺序烯烃复分解/光氧化还原催化。

钌（II）亚烷基络合物（例如Grubbs的第一代和第二代催化剂）会被2,2'-联吡啶进行配体取代，这很容易导致常见的光氧化还原催化剂Ru（bpy）3 2+。通过闭环复分解（RCM）/光氧化还原ATRA反应，证明了该催化剂转化在顺序烯烃复分解/光氧化还原催化中的应用。
