Abstract
Air- and moisture-stable (NHC)Pd(allyl)Cl complexes have been used in Suzuki-Miyaura cross-coupling, catalytic dehalogenation of aryl halides, and aryl amination. A general system involving (IPr)Pd(allyl)Cl as catalyst and NaOtBu as base has proven to be highly active for all reactions. Microwave-assisted processes have afforded yields similar to those of the conventionally heated analogous reactions.
