The reaction of thiocarbonyl fluoride, generated from difluorocarbene, with various amines under mild conditions is described. Secondary amines, primary amines, and o‐phenylenediamines are converted to thiocarbamoyl fluorides, isothiocyanates, and difluoromethylthiolated heterocycles, respectively. Thiocarbamoyl fluorides were further transformed into trifluoromethylated amines by using a one‐pot process
描述了在温和条件下由二氟卡宾生成的硫代羰基氟化物与各种胺的反应。仲胺,伯胺和邻苯二胺分别转化为硫代氨基甲酰氟,异硫氰酸酯和二氟甲基硫代杂环。硫氨甲酰氟通过一锅法进一步转化为三氟甲基化胺。硫代羰基氟化物在原位生成,并在温和条件下在一锅中迅速完全转化;因此,不需要特殊的安全预防措施。
