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。

The invention provides a method of selectively fluorinating an organic compound at an unactivated saturated sp3 hybridised carbon atom, the method comprising reacting the compound with a fluorinating agent containing an N-F bond. The carbon atom may be, for example, a tertiary carbon atom or a secondary carbon atom. The carbon atom may form part of a cyclic structure. The fluorinating agent may be any electrophilic fluorinating agent containing an N-F bond. Preferably, the fluorinating agent is an N-fluorinated diazoniabicycloalkane.
