Abstract

The novel catalytic reaction for bromolactonization of alkenoic acids is reported. When iodobenzene is used as recyclable catalyst in combination with Oxone® as terminal oxidant, the cyclization of various 4‐pentenoic acids with sodium bromide is easily carried out in CF~3~CH~2~OH at room temperature and giving five‐membered bromolactones in good yields. J. Heterocyclic Chem., 2011.
