Phenoxide‐Catalyzed Synthesis of Trifluoromethylated Alkenes from Trifluoromethylated Alkyl Bromides

α‐CF 3 ‐substituted alkenes are a class of highly important building blocks. Herein, a new phenol‐based catalytic system is developed that facilitates the elimination of trifluoromethylated alkyl bromides to produce trifluoromethylated alkenes‐a process previously deemed challenging. This method is distinguished by its mild reaction conditions, extensive substrate compatibility, and high chemo‐selectivity and regioselectivity. This facile elimination can be plausibly attributed to phenoxide anion–secondary trifluoromethylated alkyl bromides weak interactions.
