yaryl)ethanols (6c–g) by reacting Ruppert’s reagent, (trifluoromethyl)trimethylsilane (TMSCF3), with appropriate substrates in the presence of a catalytic amount of cesium fluoride are described. A versatile route to the synthesis of substituted aryl difluoromethane derivatives (8h–l, 10m, 12n, o, 14p) and the reactivity of substituted aromatic aldehydes towards bis(2-methoxyethyl)aminosulfur trifluoride
高效,高产率地合成2,2,2-三氟-1-(N,N-二烷基氨基苯基)-乙醇(3a,b)和2,2,2-三氟-1-(羟基芳基)乙醇(6c – g)描述了在催化剂量的氟化铯存在下,通过使鲁珀特氏试剂(三氟甲基)三甲基硅烷(TMSCF 3)与合适的底物反应。合成取代的芳基二氟甲烷衍生物(8h – l,10m,12n,o,14p的通用方法)),还研究了取代的芳族醛对双(2-甲氧基乙基)氨基三氟化硫(Deoxofluor™)的反应性。
