photochemical conditions, thus yielding N‐acyl nitrenes. Described herein is a light‐induced ruthenium‐catalyzed N‐acyl nitrene transfer to sulfides and sulfoxides by decarboxylation of 1,4,2‐dioxazol‐5‐ones at room temperature, thus providing direct access to N‐acyl sulfimides and sulfoximines under mild reaction conditions. In addition, a one‐pot sulfur imidation/oxidation sequence catalyzed by a single
1,4,2-二恶唑-5-酮是五元杂环,已知在热或光化学条件下会脱羧,从而生成N-酰基腈。本文描述了一种光诱导的钌催化的N-酰基氮烯在室温下通过1,4,2-二氧杂唑-5-酮的脱羧反应转化为硫化物和亚砜的化合物,因此可以在温和的条件下直接接触N-酰基磺酰亚胺和亚磺酰亚胺反应条件。此外,还报道了由单个钌络合物催化的一锅硫酰亚胺化/氧化序列。
