2-[18F]Trifluoromethylated indoles were obtained from 2-(chlorodifluoromethyl)indoles via a metal-free nucleophilic halogen exchange (halex) reaction with [18F]fluoride, whereat the comparably mild conditions are enabled by a supportive elimination-addition mechanism on the 2-methyl group.
2-[ 18 F] 三氟甲基化吲哚是通过与 [ 18 F] 氟化物的无金属亲核卤素交换 (halex) 反应从 2-(氯二氟甲基) 吲哚获得的,而相对温和的条件是通过支持性消除-加成机制实现的在 2-甲基上。
