-Iodosuccinimide catalyzed, visible-light-induced oxidative decarboxylative cross-coupling between cinnamic acids and NH-sulfoximines is presented. This strategy results in the formation of α-keto--acyl sulfoximines the construction of two new CO bonds and one C-N bond. The -generated -iodosulfoximine serves as the light-absorbing species in the absence of any external photosensitizer. The keto carbonyl and amidic carbonyl oxygen in the resulting product originate from dioxygen and water respectively.
碘代琥珀酰亚胺催化、可见光诱导的肉桂酸与 NH-亚磺酰胺的氧化脱羧交叉偶联反应被提出。该策略导致了 α-酮-酰基亚磺酰胺的形成，构建了两个新的 C-O 键和一个 C-N 键。在没有任何外部光敏剂的情况下，生成的 -碘代亚磺酰胺作为光吸收物质。生成产物中的酮羰基和酰胺羰基氧分别来源于氧气和水。
