Abstract The synthesis of (2‐Phenoxy)benzothiazole and (2‐Phenylthio)benzothiazole has been demonstrated in the presence of iron catalyst under mild reaction conditions. Library of target compounds are prepared under optimized reaction conditions. Both electron donating and electron withdrawing substituent's are readily carried out the reaction to provide their respective target products in moderate to good yield. Mechanistic studies have suggested that the methodology involves intra molecular C‐S cross‐coupling approach.
