Merging Photoredox Catalysis with Lewis Acid Catalysis: Activation of Carbon-Carbon Triple Bonds.
Chemical Communications(2016)
摘要
Here, we demonstrate that merging photoredox catalysis with Lewis acid catalysis provides a fundamentally new activation mode of C-C triple bonds, to achieve the bond-forming reaction of alkynes with weak nucleophiles. Using a synergistic merger of Eosin Y and Cu(OTf)2, a highly efficient cyclization reaction of arene-ynes was developed.
