C(2)-bromoarylation reaction and intramolecular CO bondformation from azulene-1-carboxylic acids and di(2-bromoaryl)iodonium salts produced azulenolactones in one pot. The sequential reaction proceeded smoothly through the copper(I)-mediated cyclization of 2-(2-bromoaryl)azulene-1-carboxylic acids derived from the regioselective iridium(III)-catalyzed C(2)-bromoarylation reaction without decarboxylation
