Three-Component Carbosulfonylation of Alkenes via Single-Atom Nickel Photocatalysis

Key Points

• The study aims to develop a sustainable method for the carbosulfonylation of vinyl amides using a nickel-based photocatalyst.
• Utilized a recyclable bifunctional poly(heptazine imide) photocatalyst with single-atom Ni sites.
• Conducted reactions under mild conditions with low catalyst loadings (0.43-0.86 mol %).
• Examined the formation of diverse vicinal aminosulfones.
• Achieved efficient carbosulfonylation of vinyl amides.
• Produced a variety of vicinal aminosulfones with high yield.
• Confirmed the robustness and recyclability of the photocatalyst.
