Abstract
<jats:title>Abstract</jats:title><jats:p>Incorporation of sulfur dioxide into organic compounds is achieved by a photocatalytic approach using sensitizers made from earth‐abundant chromium(III) ions and visible light leading to sulfones and sulfonamides. We employed three different chromium(III) sensitizers <jats:bold>[Cr(ddpd)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup></jats:bold>, <jats:bold>[Cr(bpmp)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup></jats:bold> and <jats:bold>[Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup></jats:bold> with long excited state lifetimes and different ground and excited state redox potentials as well as varying stability under the reaction conditions (ddpd=<jats:italic>N</jats:italic>,<jats:italic>N’</jats:italic>‐dimethyl‐<jats:italic>N</jats:italic>,<jats:italic>N</jats:italic>’‐dipyridin‐2‐yl‐pyridine‐2,6‐diamine; bpmp=2,6‐bis(2‐pyridylmethyl)pyridine; tpe=1,1,1‐tris(pyrid‐2‐yl)ethane). Key reaction steps of the catalytic cycles are identified by electrochemical, luminescence quenching, photolysis, laser flash photolysis and catalytic experiments delivering a detailed picture of the challenges in these transformations. The reactivity of the reduced chromium complex was identified as a key property to explain the reaction outcomes. Initial cage escape yield determinations with <jats:bold>[Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup></jats:bold> revealed that desired photoreactions occur with unusually high quantum efficiencies, whereas side reactions are almost unproductive.</jats:p>
