Trifluoromethanesulphonylhydroxamic acid, CF3SO2NHOH, is shown to release HNOunder physiological pHconditions. A two‐step synthesis is presented with the first complete characterization of CF3SO2NHOH. This molecule rapidly decomposes in neutral aqueous solution to cleanly release HNO and CF3SO2−, which was demonstrated using the HNO traps TXPTS and HOCbl, and by 19F NMR spectroscopy.
三氟甲磺酰基异羟肟酸CF 3 SO 2 NHOH在生理pH条件下释放出HNO。首先完成CF 3 SO 2 NHOH的表征,然后进行两步合成。这种分子迅速分解在中性水溶液中干净地释放HNO和CF 3 SO 2 - ,其中用的是HNO陷阱TXPTS和HOCbl,和由显示出19 F NMR光谱。
