fungus Beauveria bassiana predominantly in the 4-position relative to the electron-rich substituent. In cases involving fluorinated methylene groups potentially capable of hydroxylation, however, defluorination and formation of a ketone was observed. The formation of the ketone can be explained by primary hydroxylation to form an unstable geminal fluorohydrin, which is subsequently dehydrofluorinated
早期的研究表明,N-苯基氨基甲酸环烷基酯主要在富电子取代基的 4 位被真菌白僵菌羟基化。然而,在涉及可能能够羟基化的氟化亚甲基的情况下,观察到脱氟和酮的形成。酮的形成可以通过伯羟基化形成不稳定的孪生氟代醇来解释,其随后被脱氟化氢。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
