    4,6-Dichloropyrimidine

    4,6-???????? C??? ??, ??, ??

    ??? ??

    Yellow Solid

    ??

    4,6-Dichloropyrimidine was used in the synthesis of N-substituted azacalix[4]pyrimidines. It was used as starting reagent for the synthesis of disubstituted pyrimidines by tandem amination and Suzuki-Miyaura cross-coupling. It was also used in a biarylpyrimidine synthesis involving biaryl cross-coupling.

    ?? ??

    Cyclic voltammograms of 4,6-dichloropyrimidine shows three cathodic waves, arising from sequential cleavage of carbon-chlorine bonds as well as the reduction of pyrimidine.
