Rhodium(i)-catalyzed 1,4-conjugate arylation toward β-fluoroalkylated electron-deficient alkenes: a new entry to a construction of a tertiary carbon center possessing a fluoroalkyl group
β-Trifluoromethylated ketones were synthesized from the corresponding α-trifluoromethylated styrenes and aromatic carboxylic acids by photoredox catalysis. This method involves phosphoranyl radical promoted deoxygenation of aromatic acids and hydroacylation of α−CF3 styrenes with the generated acyl radicals.
