  A Facile Synthesis of Isomeric C-(2,2,2-Trifluoroethyl)anilines

  摘要：

  Three isomers of C-(2,2,2-trifluoroethyl) aniline were prepared on a multigram scale from readily available nitrophenylacetic acids in two steps. First, the carboxy groups of the latter were converted into the trifluoromethyl moieties by treatment with sulfur tetrafluoride. The obtained 2,2,2-trifluoroethyl-substituted nitrobenzenes were reduced catalytically into the corresponding anilines.

  derivatives under mild conditions remains an important goal for medicinal and agricultural chemists. One representative example of a desirable transformation involves the conversion of aromatic and heteroaromatic ketones and aldehydes into aryl and heteroaryl β,β,β-trifluoroethylarenes and -heteroarenes. The traditional approach for this net transformation involves stoichiometric metals and/or multistep reaction

  在温和条件下将简单和常见的底物转化为氟烷基衍生物的能力仍然是医药和农业化学家的一个重要目标。理想转化的一个代表性实例包括将芳族和杂芳族酮和醛转化为芳基和杂芳基β,β,β-三氟乙基芳烃和-杂芳烃。这种净转化的传统方法涉及化学计量的金属和/或多步反应序列，它们消耗过多的时间、材料和劳动力资源，同时提供低产率的产品。为了补充这些传统策略，我们报告了一种一锅式无金属脱羧程序，用于从容易获得的酮和醛中获取 β,β,β-三氟乙基芳烃和 - 杂芳烃。这种方法有几个好处，
