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.
该发明涉及公式##STR1##中X为2-吡啶基或2-嘧啶基的2-取代的5-乙烯基嘧啶化合物,未取代或取代为甲基或乙基基团。公式(I)的化合物适用于制备形成复合物或被复合物化的、未交联或交联的聚合物。由此可获得的复合物聚合物可用作催化剂。与Pd复合的聚合物特别适用于反式乙烯化反应。由公式(I)的化合物获得的非复合聚合物适用于用作不同应用的金属离子萃取剂。
