Carbotrifluoromethylation of Allylic Alcohols via 1,2‐Aryl Migration Promoted by Visible‐Light‐Induced Photoredox Catalysis.

Visible‐light‐enabled photocatalytic carbotrifluoro‐methylations of allylic alcohols and sodium triflinate were explored through 1,2‐migration of an aryl group, affording an efficient method for synthesis of β‐trifluoromethyl‐α‐substituted carbonyl compounds under mild reaction conditions. This catalyst system is well tolerant of various synthetically useful functional groups. [ABSTRACT FROM AUTHOR]
