volatility, storage instability, toxicity, and explosiveness. We report the application of trifluoroacetaldehyde N-tosylhydrazone as a CF3CHN2 precursor capable of generating in situ trifluorodiazoethane under mild basic conditions. Copper-catalyzed P–H, O–H, S–H, and C–H insertion reactions of trifluoroacetaldehyde N-tosylhydrazone revealed its wide applicability in the synthesis of trifluoroethyl-containing
三氟重氮乙烷是一种被广泛研究的三氟乙基化试剂,适用于制备大量的含氟有机分子。然而,CF 3 CHN 2具有一些缺点,例如挥发性,储存不稳定性,毒性和爆炸性。我们报告了三氟乙醛N-甲苯磺酰as作为CF 3 CHN 2前体的应用,该前体能够在温和的碱性条件下原位生成三氟重氮乙烷。铜催化的三氟乙醛N-甲苯磺酰hydr的PH,OH,SH和CH插入反应表明了其在含三氟乙基物质合成中的广泛应用。
