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.
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。
