Remarkable Anion and Cation Effects on Stille Reactions in Functionalised Ionic Liquids

Task-specific ionic liquids bearing nitrile functional groups attached to the cation and nitrogen-donor-containing anions strongly affect the efficiency of the Stille cross-coupling, influencing the nature of the catalyst and its stability. The relative strengths of the coordinating power of the cations and anions are varied and compared, and under certain conditions nanoparticles are observed.
