A photocatalytic reaction of N ‐(2‐vinylphenyl)amides, DABCO⋅(SO 2 ) 2 and arenediazonium tetrafluoroborates for the synthesis of 4‐((arylsulfonyl)methyl)‐4 H ‐benzo[ d ][1,3]oxazines under mild conditions is reported. This synthetic approach is enabled by merging photoredox catalysis and insertion of sulfur dioxide via a radical process. The specific role of photoredox catalysis in this transformation is supported by mechanistic investigations and theoretical calculations.
