Fe(III)/Pyridine-Mediated Decarboxylative Nitration of α,β-Unsaturated Acids with Iron Nitrate

A novel and efficient method for the synthesis of ( E )-nitroolefins in moderate to excellent yields is developed by Fe(III)/pyridine-mediated decarboxylative nitration of α,β-unsaturated acids with iron nitrate. A series of α,β-unsaturated acids are well tolerated in this procedure.
