Introduction of [18F]fluoride ion into the aromatic core of phenylazocarboxylic esters was achieved in only 30 seconds, with radiochemical yields of up to 95 % (85(±10) %). For labeling purposes, the resulting 18F‐substituted azoester can be further converted in radical‐arylation reactions to give biaryls, or in substitutions at its carbonyl unit to produce azocarboxamides.
仅在30秒内即可将[ 18 F]氟离子引入到苯偶氮羧酸酯的芳族核中,放射化学产率高达95%(85(±10)%)。出于标记目的,可以将所得的18 F-取代的偶氮酯进一步在自由基芳构化反应中转化为联芳基,或在其羰基单元上进行取代以生成偶氮羧酰胺。
