摘要

Carbon monoxide, as a C1 synthon, plays a fundamentally important role in modern chemical synthesis.Despite great achievements, the development of sustainable and effective CO conversion methods is still in high demand [1,2].Transitionmetal-catalyzed carbonylation of halides has been established as a powerful platform for assembling valuable carbonyl compounds,including (thio)esters, amides, aldehydes and ketones [3].Nevertheless, high barrier owing to the strong coordination of CO with transition metals would disfavor the oxidative addition of metal catalysts to halides, which results in the requirements of high temperature and highly active substrate.In the past decades, Alexanian groups [4] and Ryu groups [5], respectively used electron-rich catalysts and ultraviolet light to facilitate oxidative addition, realizing carbonylation of alkyl iodines with strong nucleophilic reagents.
