摘要：
A highly selective palladium bis(acetoacetonate)/copper(I) chloride [Pd(acac)(2)/CuCl] catalytic system for the preparation of dibenzopyranones has been developed. Tandem decarboxylative coupling and lactonization can be realized in one pot using commercially available starting materials. The reaction proceeded well for a range of different substrates.
