Efficiency of ionic liquid supported organotin reagents in Stille cross-coupling reactions involving aryl bromides has been investigated. In a general manner, products were isolated with good yields by using a very simple catalytic system without the need of solvent, ligand, or additives. The organotin compounds were recycled without loss of activity and the contamination by tin was limited and controlled
已经研究了离子液体负载的有机锡试剂在涉及芳基溴化物的 Stille 交叉偶联反应中的效率。通常,通过使用非常简单的催化系统而无需溶剂、配体或添加剂,可以高产率地分离产物。有机锡化合物在不损失活性的情况下回收利用,并且锡污染得到限制和控制([Sn] < 3 ppm)。
