transformation from sulfinic acids to sulfoxides under visible-light irradiation in the presence of N-heterocyclic carbene is established. Various alkyl groups from four-substituted Hantzsch esters or Meyer nitriles are smoothly converted to the corresponding sulfoxides through a radical coupling pathway in the presence of 1,1-carbonyldiimidazole. This method allows sulfoxide synthesis to refrain from
建立了在 N-杂环卡宾存在下在可见光照射下从亚磺酸到亚砜的光催化转化。在 1,1-羰基二咪唑存在下,来自四取代 Hantzsch 酯或 Meyer 腈的各种烷基通过自由基偶联途径顺利转化为相应的亚砜。该方法允许亚砜合成避免依赖硫化物的氧化,并为制备亚砜提供了替代途径。
