Trifluoromethylated tertiary allylic alcohols, obtained from trifluoromethylation of several conjugated enones, undergo oxidative rearrangements to 3-trifluoromethyl-2-cycloalkenones with pyridinium chlorochromate in the presence of a small amount of concentrated H2SO4.
由几种共轭烯酮的三氟甲基化制得的三氟甲基化叔烯丙醇,在少量浓H 2 SO 4的存在下,与氯铬酸吡啶鎓发生氧化重排反应,生成3-三氟甲基-2-环烯酮。
