摘要：

A photochemically induced carbon monoxide-inclusive four-component carbonylation reaction has been delineated, facilitating the diacylation of styrenes with acyl azolium salts to synthesize valuable 1,4-diketone compounds with moderate to good yields. This process proceeds by generating acyl radicals from the Hantzsch esters and carbon monoxide, which subsequently add to the terminal position of styrenes. Then, under light irradiation, the newly generated carbon radical can further react with activated acyl azolium salts to finish the desired 1,4-diketone products.
