The amino alcohol meglumine solubilizes organic compounds in water and enforces the formation of electron donor acceptor (EDA) complexes haloarenes with indoles, anilines, anisoles or thiols, which are not observed solvents. UV-A photoinduced transfer within EDA induces mesolytic cleavage halide ion radical recombination arenes leading, after rearomatization proton loss to C-C C-S coupling products. Depending on substitution pattern selective unique cross-couplings observed. UV NMR...

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

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