Reactions of alkyl- or aryl-lithiums with decafluorobenzil gave adducts which undergo rapid pentafluorophenyl migration. A variety of products were obtained after hydrolysis, depending on the lithio-derivative used: ketoalcohols, a benzo[b]furan derivative (from C6F5Li), and bis(pentafluorophenyl)methyl pentachlorobenzoate (from C6Cl5Li). The mechanisms of these processes are discussed. Some analogous
烷基锂或芳基锂与十氟苯甲酰的反应生成加合物,该加合物经历了快速的五氟苯基迁移。水解后,根据所使用的硫代衍生物,可得到多种产品:酮醇,苯并[ b ]呋喃衍生物(来自C 6 F 5 Li)和双(五氟苯基)五氯苯甲酸二甲酯(来自C 6 Cl 5 Li)。 。讨论了这些过程的机制。描述了一些类似的苯甲酰反应用于比较,并研究了这些过程中各组的相对迁移能力。
