Radical Nitration-Debromination of α-Bromo-α-fluoroalkenes as a Stereoselective Route to Aromatic α-Fluoronitroalkenes—Functionalized Fluorinated Building Blocks for Organic Synthesis

“…Considering the high stereoselectivity observed during similar radical nitration of unsubstituted styrenes, we also envisioned high stereoselectivity for the nitration-debromination of fluoro-bromostyrenes 2 . The formation of simple nitrostyrenes in a trans -configuration is quite predictable; however, to the best our knowledge, cis -isomers are much less stable compounds . Stereoselective formation of 1-fluoro-1-nitroalkenes 1 can be explained by the formation of intermediate A (Scheme ).…”
