Polychloromethylation‐Initiated Radical 1,2‐Aryl Migration of α,α‐Diarylallyl Alcohols via Visible‐Light Photoredox Catalysis

Abstract A visible‐light induced radical 1,2‐aryl migration of α,α‐diarylallyl alcohols was developed under mild and metal‐free conditions. Commercially available CHCl 3 and CH 2 Cl 2 were used as tri‐ and dichloromethyl radical precursors. Structurally diverse β‐polochloromethylated ketones were obtained in good to moderate yields via neophyl‐type rearrangement. Besides, the polychloromethyl group can be easily transformed into other useful functional groups.
