Herein, we describe a valuable method for the introduction of the [18F]CF3 group into arenes with highly improved specific activity by the reaction of [18F]trifluoromethane with aryl iodides or aryl boronic acids. This [18F]trifluoromethylation reaction is the first to be described in which the [18F]CF3 products are generated in actual trace amounts and can therefore effectively be used as PET tracers
在此,我们描述了一种有价值的方法,可通过[ 18 F]三氟甲烷与芳基碘化物或芳基硼酸的反应将[ 18 F] CF 3基团引入具有较高比活性的芳烃中。该[ 18 F]三氟甲基化反应是首次描述的,其中[ 18 F] CF 3产物以实际痕量产生,因此可以有效地用作PET示踪剂。就可能的芳基碘化物和芳基硼酸底物而言,该方法显示出广泛的范围,并且具有良好的转化率。特别是,发现硼酸的[ 18 F]三氟甲基化性能优于[ 18关于转化率,反应条件和动力学,卤代芳基前体的F]三氟甲基化反应。
