Enforced Electronic‐Donor‐Acceptor Complex Formation in Water for Photochemical Cross‐Coupling
The amino alcohol meglumine solubilizes organic compounds in water and enforces the
formation of electron donor acceptor (EDA) complexes of haloarenes with indoles, anilines,
anisoles or thiols, which are not observed in organic solvents. UV‐A photoinduced electron
transfer within the EDA complexes induces the mesolytic cleavage of the halide ion and
radical recombination of the arenes leading, after rearomatization and proton loss to C− C or
C− S coupling products. Depending on the substitution pattern selective and unique cross …

The sugar alcohol meglumine enhances the solubility of organic compounds in water and
enforces the formation of electron donor–acceptor (EDA) complexes, enabling
photochemical C− C and C− S cross-coupling transformations without sensitizers. The light-
driven redox-neutral protocol connects haloarenes with indoles, anilines, anisoles, and
thiols, as reported by Burkhard König and co-workers in their Research Article
(e202218775).
