compounds labeled with short-lived 11C. With the sensitizers, the synthesis of [carbonyl-11C]esters and acids from alkyl iodides, [11C]carbon monoxide, alcohols, and water provided up to 75-85% decay-corrected radiochemical yields in 6-min reactions under mild conditions. Acetone was used as a sensitizer in preparing 13C-substituted 1,10-decanedicarboxylic acid from (13C)carbon monoxide.
[反应:见正文]证明了几种光敏剂在光引发的自由基羰基化反应中的增强作用,并将其用于加速以短寿命11C标记的化合物的合成。使用敏化剂,在温和的条件下,在6分钟的反应中,由烷基碘,[11C]一氧化碳,醇和水合成[羰基11C]酯和酸,可提供高达75-85%的经衰变校正的放射化学收率。丙酮用作由(13C)一氧化碳制备13C取代的1,10-癸烷二羧酸的敏化剂。
