摘要：A recyclable Ruthenium tris [4,4'-bis (dinonylmethyl)-2,2'-bipyridine] (Ru[(DNM)(2)bpy](3)(2+)) photocatalyst (PC) was synthesized. Hexane-phase-selective solubility allowed its simple and efficient separation from reaction products via solvent extraction. The excellent catalytic activity and recoverability were demonstrated in batch and flow perfluoroalkylation reactions of coumarin under visible-light irradiation. High reaction rates and easy reusability of the catalyst make this approach attractive for large-scale applications. (C) 2018 Elsevier Ltd. All rights reserved.
