An efficient method for phenylselenylation of ethers using a diphenyl diselenide–tributylphosphine–molecular oxygen system has been successfully developed. The reactions proceed under mild conditions in good to high yield. A plausible reaction mechanism for the phenylselenylation via C(sp³)−H activation was also proposed, and a tributylphosphonium peroxide radical was assumed as an important intermediate in the C(sp³)−H activation.

在温和的反应条件下，使用二苯二硒化物-三丁基膦-分子氧系统进行醚的苯甲磺酰化

已经成功开发了使用二苯二硒化物-三丁基膦-分子氧系统对醚进行苯硒基化的有效方法。反应在温和的条件下以高至高收率进行。还提出了通过C（sp ³）-H活化进行苯硒基化的合理反应机理，并假定过氧化三丁基phosph自由基是C（sp ³）-H活化的重要中间体。
