All articles of this category The reactions of several substituted halopyrimidines with methyl vinyl in the presence of palladium diacetate-triphenylphosphine ketone complex in triethylamine are investigated. In the reactions of bromopyrimidines, the usual olefinic substituted products are obtained. But on using iodopyrimidines, the addition of pyrimidine to the carbon-carbon double bond of methyl vinyl ketone occurs to afford substituted 5-(3-oxobutyl)pyrimidines. Possible mechanisms are presented.
