We report here the synthesis of a novel family of N-CF₃ hydrazines from a direct way involving the available and cheap Langlois reagent (CF₃SO₂Na). These derivatives have shown very high stability whatever the conditions used and are excellent precursors for building previously inaccessible N-CF₃ functionalized compounds, such as substituted hydrazides, hydrazine-amino-acids, hydrazones, N-aziridines and pyrazoles.

偶氮二羧酸自由基三氟甲基化合成N-CF3肼

我们在此报告了一种新型N -CF ₃肼家族的合成，该方法涉及可用且廉价的朗格洛伊试剂 (CF ₃ SO ₂ Na)的直接方式。无论使用何种条件，这些衍生物都显示出非常高的稳定性，并且是构建以前无法获得的N -CF ₃官能化化合物的优秀前体，例如取代酰肼、肼氨基酸、腙、N-氮丙啶和吡唑。
