protocol from aromatic conjugated ketones to 1,1,1‐trifluoro‐2,5‐diketones and 2‐(trifluoromethyl)furans was developed through magnesium‐promoted reductive trifluoroacetylation and acid‐facilitated deacetalization in moderate to high yields with good substrate tolerance. Two kinds of trifluoromethylated compounds were selectively synthesized by control of reaction conditions, respectively.
