Abstract
Sterically demanding 1,3-dialkyl-3,4,5,6-tetrahydropyrimidinium salts as NHC precursors in combination with palladium acetate provided active catalysts for the cross-coupling of aryl chlorides and bromides under mild conditions. The catalytic system was applied to the Heck, Suzuki and benzaldehyde coupling reactions.
