Ionic Liquid Supported Organotin Reagents: Green Tools for Stille Cross‐Coupling Reactions with Brominated Substrates

Abstract

Abstract 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 ([Sn] < 3 ppm).
