A new radiosynthetic protocol for the preparation of [(11)C]aryl nitriles has been developed. This process is based on the direct reaction of in situ prepared L·Pd(Ar)X complexes (L = biaryl phosphine) with [(11)C]HCN. The strategy is operationally simple, exhibits a remarkably wide substrate scope with short reaction times, and demonstrates superior reactivity compared to previously reported systems. With this procedure, a variety of [(11)C]nitrile-containing pharmaceuticals were prepared with high radiochemical efficiency.
已开发出一种用于制备[(11)C]芳基腈的新的放射性合成方案。该方法基于原位制备的L·Pd(Ar)X配合物（L = 联芳基膦）与[(11)C]HCN的直接反应。该策略操作简单，底物范围广，反应时间短，与先前报道的体系相比显示出优异的反应活性。通过该方法，以高放射化学效率制备了多种含[(11)C]腈的药物。
