The reactivity of Pd-PEPPSI (Pyridine, Enhanced, Precatalyst, Preparation, Stabilization, and Initiation) precatalysts in the Stille-Migita cross-coupling reaction between heteroaryl stannanes and aryl or heteroaryl halides was evaluated. In general, Pd-PEPPSI-IPent (IPent=diisopentylphenylimidazolium derivative) demonstrated high efficiency over a variety of challenging
