Simple and readily available ketones have been identified to promote the visible-light-promoted aerobic oxidation of sulfides and sulfoxides to sulfones. We report a simple and environmental-friendly oxidation protocol of sulfides to sulfones. Various sulfides were efficiently oxidized into sulfones with O2 as sustainable terminate oxidant, readily available thioxanthone as the photocatalyst and 3-pentanone
已确定简单且容易获得的酮可促进可见光促进的
硫化物和亚砜有氧氧化为砜。我们报告了一种简单且环保的
硫化物氧化为砜的方法。各种
硫化物被有效地氧化成砜,O 2作为可持续的终止氧化剂,容易获得的
噻吨酮作为光催化剂,
3-戊酮(DEK)作为溶剂。该协议允许不同的官能团,包括卤素、酮、酯、
氰基、杂环甚至环丙基。通过 GC 和 HRMS 检测 DEK 中的有氧氧化反应,揭示了关键活性中间体的生成。
