The iodine-promoted triflylation of 1,4-benzoquinones with cheap and easily available sodium trifluoromethanesulfinate is achieved under mild conditions. A series of aryl triflones were obtained in moderate to good yields. The method could also be extended to triflylation of 1,4-benzoquinone monoamines and perfluoroalkanesulfonylation with sodium perfluoroalkanesulfinates.

1,4-苯醌与三氟甲烷亚磺酸钠的三氟甲基化

在温和的条件下，用便宜且容易获得的三氟甲烷亚磺酸钠实现了碘促进的1,4-苯醌的三氟甲基化。以中等至良好的产率获得了一系列芳基三氟甲磺酸。该方法还可以扩展到1，4-苯醌单胺的三氟甲基化和全氟烷磺酸亚磺酸钠的全氟烷磺酰基化。
