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
已开发出一种用于制备 [(11) C] 芳基腈的新放射合成协议。该过程基于原位制备的 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,表现出非常广泛的底物范围和较短的反应时间,并且与之前报道的系统相比表现出优异的反应性。通过该程序,以高放射化学效率制备了多种含 [(11) C] 腈的药物。
