[18F]arylCF3 and [18F]arylCHF2 derivatives from arylCF2Br and arylCHFCl precursors applying a silver-mediated halogen exchange with [18F]fluoride. In the absence of Ag(I)OTf, no reaction takes place at room temperature for both classes of substrates; this result demonstrates the beneficial role of silver(I) as a means to induce 18F-incorporation under very mild conditions.
我们报告了应用银介导的卤素交换与 [18F] 氟化物从芳基CF2Br 和芳基CHFCl 前体合成[18F]芳基CF3 和[18F]芳基CHF2 衍生物。在没有 Ag(I)OTf 的情况下,这两类底物在室温下都不会发生反应;该结果证明了银 (I) 作为一种在非常温和的条件下诱导 18F 掺入的手段的有益作用。
