Studies on Pyrimidine Derivatives. XXX. The Palladium-Catalyzed Cross-Coupling Reaction of Iodopyrimidines with Terminal Olefinic Compounds

Abstract

The influence of triphenylphosphine, used as a ligand, on the palladium-catalyzed cross-coupling reaction of iodopyrimidines with olefins such as ethyl acrylate, acrylonitrile, and styrene was investigated. In general, the addition of triphenylphosphine was concluded to retard the reaction in the pyrimidine series. The effect of triphenylphosphine in the monoazine series is also discussed.
