Aniline-derived diaryliodoniumsalts were synthesized and functionalized in good to excellent yields by judicious utilization of electron-withdrawing protecting groups. This simple approach opens another route to radiolabeling amino arenes in relatively complex molecules, such as flutemetamol.

A simple and facile one-pot reaction has been developed to afford a diverse range of N,N′-disubstituted benzimidazolones and imidazopyridinones containing two differently substituted N atoms. A cooperative Pd(II)/Ag(I) system promotes the sequential addition/intramolecular C–H amidationreaction of (hetero)aromatic amines and isocyanates, leading to the formation of two C–N bonds. A mechanism involving
已经开发出一种简单且容易的一锅反应,以提供包含两个不同取代的N原子的N,N'-二取代的苯并咪唑酮和咪唑并吡啶并酮的不同范围。协同的Pd(II)/ Ag(I)系统促进了(杂)芳族胺和异氰酸酯的顺序加成/分子内CH-H酰胺化反应,导致形成两个C-N键。一种机制,涉及在Ag 2 CO 3氧化剂和Pd(OAc)2存在下通过单电子转移(SET)生成的自由基中间体提出了路易斯酸。该协议使用易于获得的起始原料,良好的官能团耐受性和高效率,提供了一种操作简便,简单且可靠的方法。
