✦ Synopsis

The electrochemical reduction of a series of 2-haloaryl ethers intramolecular cyclization-carboxylation reaction is carried out in single-compartment cells and is catalyzed by containing allyl and propargyl groups under CO 2 allows the synthesis of benzofuranacetic acid derivatives. This novel [Ni(cyclam)Br 2 ].
