N-(trifluoromethyl)amides along with aromatic N-(difluoromethylene)-N-(trifluoromethyl)amine derivatives has been developed. The starting materials are the easily available isothiocyanates, and the fluorinating reagent is the commercially available bromine trifluoride. The reaction is performed under mild conditions, and the fluorinated amides and amines are produced in moderate to high yields.
已经开发了多种不同的脂族,芳族和杂环N-(三氟甲基)酰胺与芳族N-(二氟亚甲基)-N-(三氟甲基)胺衍生物的合成。起始原料是易得的异硫氰酸酯,氟化试剂是可商购的三氟化溴。该反应在温和的条件下进行,并且氟化酰胺和胺的产率中等至高。
