Activation of Alkyl Chlorides Enabled by Zirconocene and Photoredox Catalysis

C–Cl bond cleavage of unactivated alkyl chlorides with zirconocene and photoredox catalysis has been achieved. The present protocol exhibited a broader scope of alkyl chlorides compared to the preceding methods with titanocene. This scope expansion could be attribut-ed to the zirconium metal center rendering the C–Cl bond cleavage more endergonic and lowering the transition states.
