Ketones are reported to be conveniently converted into their α-tolylsulfinylated derivatives. This new procedure is based on the reaction of their corresponding trimethylsilyl enol ethers with p-toluenesulfinyl p-tolylsulfone in the presence of tris(dimethylamino)sulfur trimethylsilyldifluoride (TAS-F). Considering that β-ketosulfoxides are key intermediates for the preparation of α,β-unsaturated ketones
摘要 据报道,酮可以方便地转化为它们的 α-甲苯基亚磺酰化衍生物。这种新方法基于在三(二甲氨基)硫三甲基甲硅烷基二氟化物(TAS-F)存在下,它们相应的三甲基甲硅烷基烯醇醚与对甲苯亚磺酰基对甲苯砜的反应。考虑到 β-酮亚砜是制备 α,β-不饱和酮的关键中间体,该过程具有相当广泛的合成相关性。
