The reactivity of Pd-PEPPSI (Pyridine, Enhanced, Precatalyst, Preparation, Stabilization, and Initiation) precatalysts in the Stille-Migita crosscoupling reaction between heteroaryl stannanes and aryl or heteroaryl halides was evaluated. In general, PdPEPPSI-IPent (IPent = diisopentylphenylimidazolium derivative) demonstrated high efficiency over a variety of challenging aryl or heteroaryl halides with thiophene-, furan-, pyrrole-, and thiazole-based organostannanes when compared with Pd-PEPPSI-IPr (IPr = diisopropylphenylimidazolium derivative). The transformations proceeded at appreciably lower temperatures (3080°C) than triarylphosphine-based Pd catalysts, improving the scope of this useful carbon-carbon bond-forming process.
