compounds by means of a CuBr2/I2/DMSO/water system is developed, enabling the fromation of various functionalized 1,2‐dicarbonyl compounds, including 1,2‐diketones, α‐keto amides and α‐keto ester. This Cu‐promoted iodine‐mediated tandem procedure employs DMSO as the oxygen atom source of the formed carbonyl group through iodonium ion formation, nucleophilic DMSO addition and C−C bond cleavage cascades.
开发了通过CuBr 2 / I 2 / DMSO /水系统串联2-炔基羰基化合物的方法,使各种官能化的1,2-二羰基化合物(包括1,2-二酮,α-酮酰胺)形成和α-酮酸酯 此铜促进的碘介导的串联过程使用DMSO作为碘原子离子形成,亲核DMSO加成和CC键断裂级联反应形成的羰基的氧原子源。
