探索了铟粉促进下,三氟乙醛甲基半缩醛或三氟甲基苯乙酮与酰肼和烯丙基溴的“一锅法”反应,高产率地得到了一系列三氟甲基高烯丙基酰肼类化合物.该方法使用价廉易得的三氟乙醛甲基半缩醛或三氟苯乙酮作为三氟甲基合成砌块,具有反应条件温和、产率高、操作简单等优点. We have explored the “one-pot” reaction of trifluoroacetaldehyde methyl hemiacetal or trifluoroacetophenone with hydrazide and allyl bromide under the promotion of indium powder and obtained a series of three Fluoromethyl methyl allylhydrazide compounds.This method uses trifluoroacetaldehyde methyl hemiacetal cheap or readily available trifluoroacetophenone ketone as a synthesis unit, with a mild reaction conditions, the production of High rate, simple operation and so on.
