Abstract

An efficient approach is reported for the direct halodecarboxylation of hydroxyaromatic acids by using a readily available N-halosuccinimide (halo = Cl, Br) as the sole promoter in ethanol at room temperature without any other catalyst or additive. This environmentally friendly route tolerates a wide substrate scope with good to excellent yields under convenient conditions.
