hydrazones of arylaldehydes with Togni's CF3 -benziodoxolone reagent, in the presence of potassium hydroxide and cesium fluoride, induces a denitrogenative hydrotrifluoromethylation event to produce (2,2,2-trifluoroethyl)arenes. This novel reaction was tolerant to many electronically-diverse functional groups and substitution patterns, as well as naphthyl- and heteroaryl-derived substrates. Advantages of this
在氢氧化钾和氟化铯的存在下,芳基醛的azo与Togni的CF3-苯并恶唑酮试剂反应,会引发脱氮加氢三氟甲基化反应,从而生成(2,2,2-三氟乙基)芳烃。这种新颖的反应可耐受许多电子多样性的官能团和取代方式,以及萘基和杂芳基衍生的底物。该方法的优点包括容易大规模获得speed前体,速度和操作简便性,并且不含过渡金属。
