complex [Cu(dmp)2Cl]Cl is introduced to visible‐light photocatalysis, being efficient but considerable more cost‐effective compared to previously established CuI photocatalysts within a broad scope of different reactions. Furthermore, this study provides UV/Vis evidence for the visible light activation of CuII complexes, suggesting an LMCT process resulting in the visible light homolysis of CuII‐Cl to give

Coupling reaction of β-perfluoroalkyl-substituted alkylhalides with Grignardreagents such as phenyl-, vinyl-, allyl-, benzyl-, and alkyl-magnesium halides was catalyzed by copper salts or complexes to give the corresponding cross-coupling products in good yields. α,ω-Diiodoalkane bearing a polyfluoroalkylene moiety also reacted with 2 equiv. of Grignardreagent in the presence of copper catalyst
Free-radical chain addition of various polyhalomethanes onto olefins can be easily initiated by electrochemically in situ generated manganic salt used in catalytic amount associated with an equimolar amount of a Mn(III)-oxidizable compound like methyl cyano- or aceto-acetate.
