%0 Journal Article %T Merging Catalysis in Single Electron Steps with Photoredox Catalysis¡ªEfficient and Sustainable Radical Chemistry %J - %D 2019 %R https://doi.org/10.1021/acscatal.9b00787 %X We describe a combination of catalysts that allows the coupling of titanocene(III) catalysis with photoredox catalysis. Oxidation of radical intermediates by a photoredox catalyst opens novel catalytic mechanisms for reductive epoxide ring opening and redox-neutral epoxide radical arylation. In the former case, the requirement of metallic reductants and stoichiometric acidic additives is bypassed %U https://pubs.acs.org/doi/10.1021/acscatal.9b00787
