Reaction of a series of model hexyl derivatives of the form C6H13–X (X=Cl, Br, I, CO2Me, COMe, CHO) with both elemental fluorine and Selectfluor™ was studied in order to assess the impact of electron withdrawing functional groups upon fluorination of an alkyl chain. Fluorination generally occurs at secondary sites, with a slight preference for those that are furthest removed from the electron withdrawing
研究了一系列形式为C 6 H 13 –X(X = Cl,Br,I,CO 2 Me,COMe,CHO)的模型己基衍生物与元素氟和Selectfluor™的反应,以评估氟的影响。烷基链氟化时的吸电子官能团。氟化通常发生在次要位置,与亲电子取代过程一致,略微偏爱从吸电子基团离得最远的位置,尽管在大多数情况下会获得氟化产物的混合物。
