《Ligand Substitution of RuII-Alkylidenes to Ru(bpy)32+: Sequential Olefin Metathesis/Photoredox Catalysis》 was published in Chemistry – A European Journal in 2020. These research results belong to Gallhof, Malte; Kell, Lukas; Brasholz, Malte. Computed Properties of C43H72Cl2P2Ru The article mentions the following:
Ruthenium(II) alkylidene complexes such as the Grubbs’ 1st and 2nd generation catalysts underwent a ligand substitution with 2,2′-bipyridine, which readily led to the common photoredox catalyst Ru(bpy)32+. The application of this catalyst transformation in sequential olefin metathesis/photoredox catalysis was demonstrated by way of ring-closing metathesis (RCM)/photoredox chlorosulfonylation reactions of dienes with tosyl chloride to afford bicyclic compounds I [R = H, 7-Me, 4-OBn, etc.; X = O, CH2; n = 0,1]. The experimental part of the paper was very detailed, including the reaction process of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Computed Properties of C43H72Cl2P2Ru)
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Computed Properties of C43H72Cl2P2Ru
