reported TFMPhos, products from nucleophilic or electrophilic trifluoromethylation of substrates, requiring one or more steps and prepared from phosphine chlorides, are very limited in structure diversity. Herein, we report a convenient and scalable (up to 100 mmol) recipe to synthesize diverse trifluoromethylphosphines via direct radical trifluoromethylation of phosphine chlorides with CF3Br in the presence
三氟甲基膦是一种稀有的膦,具有独特的吸电子特性,可导致一些独特的反应性。报道的 TFMPhos 是底物的亲核或亲电三氟甲基化产物,需要一个或多个步骤并由氯化膦制备,其结构多样性非常有限。在此,我们报告了一种方便且可扩展(高达 100 mmol)的配方,通过氯化膦与 CF 3 Br 在锌粉存在下的直接自由基三氟甲基化合成多种三氟甲基膦。
