Heck reaction of aryl and styryl iodides with styrenes was developed. The hemilabile P,N-ligand-assisted gold-catalyzed C(sp2)–C(sp2) cross-coupling can synthesize stilbenes and bistyryl complexes, with good functional-group tolerance and mild conditions. The elementary organometallic steps of migratory insertion and β-hydride elimination might be involved in this ligand-enabled Au(I)/Au(III)-catalyzed
开发了金催化的芳基碘化物和苯乙烯基碘化物与苯乙烯的 Heck 反应。半不稳定的P,N-配体辅助金催化的C(sp 2 )–C(sp 2 )交叉偶联可以合成茋和联苯乙烯配合物,具有良好的官能团耐受性和温和的条件。迁移插入和 β-氢化物消除的基本有机金属步骤可能涉及这种配体启用的 Au(I)/Au(III) 催化的与苯乙烯的 Heck 反应。
