Tang, Wei-Ke published the artcileVisible-Light-Enabled Decarboxylative Mono- and Difluoromethylation of Cinnamic Acids under Metal-Free Conditions, Category: bromides-buliding-blocks, the publication is Organic Letters (2017), 19(20), 5501-5504, database is CAplus and MEDLINE.
Several new mono- and difluoromethylation reactions of cinnamic acids using an Eosin Y catalytic system are reported. An efficient alkene fluoromethylation of α,β-unsaturated carboxylic acids, e.g., I, II, and III, was accomplished under ambient temperature and metal-free conditions, with a wide range of functional group tolerance. A mechanism that involves a radical process is proposed for this reaction.
