the behavior of the extensively used system trifluoromethanesulfonic anhydride/sulfoxide in the absence of any added nucleophilic species. We show here, with the help of 19 F NMR spectroscopy, that in the case of trifluoromethyl sulfoxides this results initially in the net reduction of the sulfoxide to a sulfane. We propose a mechanism involving sulfoxide itself as the reducing agent.
我们研究了广泛使用的系统三氟甲磺酸酐/亚砜在不添加任何亲核物质的情况下的行为。我们在这里借助 19 F NMR 光谱表明,在三氟甲基亚砜的情况下,这最初导致亚砜净还原为硫烷。我们提出了一种涉及亚砜本身作为还原剂的机制。
