Abstract
The invention relates to 2-substituted 5-vinylpyrimidines of the formula ##STR1## wherein X is 2-pyridyl or 2-pyrimidyl, unsubstituted or substituted by methyl or ethyl groups. The compounds of formula (I) are suitable for the preparation of complex-forming or complexed, uncrosslinked or crosslinked polymers. Complexed polymers obtainable therefrom may be used as catalysts. Polymers complexed with Pd are particularly suitable for transvinylation reactions. Non-complexed polymers obtainable from compounds of formula (I) are suitable for use as metal ion extractors for different applications. The 2-substituted-5-vinylpyrimidines are prepared by the reaction of 5-formyl-alpha-pyrone with a secondary amine to form an alpha-vinyl-beta-secondary-aminoacrolein which is then condensed with a substituted amidine base to give the title compounds.
