用途
用途
有機合成原料。
使用
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.
一般的な説明
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.
