Fig. 5: Hetero-dihalogenation reactions via selective p-shuttle catalysis.
a Possible product distribution. Four different products were generated via hetero-dihalogenation shuttle catalysis reactions. b Screen out different metals and solvents for optimizing the hetero-dihalogenation reaction conditions. c Scope of alkene of the photocatalytic hetero-dihalogenation. All yields are GC yields of the products unless otherwise noted. *1H-NMR yield. Reaction conditions: 0.1 mmol alkene compound, 0.17 mmol DBE, 0.95 mmol TCE, 5 mg Cu-CsPbBr3 QD catalyst, 1 mL of MeCN and irradiation using a 10 W white LED at 25 °C. †0.2 mmol alkene compound as the substrate. d Proposed mechanism of the generation of hetero-dihalogenation via metal-controlled hot electron reduction.
