In an investigation into the electrophilic nitrosation reactions of a series of 4,6-disubstituted pyrimidine derivatives, a subtle interplay between the electronic nature of the C-4 and C-6 substituents and reactivity was found where these were chloro-, mono- or disubstituted amino groups. Effects such as the presence of an aryl group or two alkyl groups on the amino moiety impede the progress of the
在对一系列4,6-二取代的嘧啶衍生物的亲电子亚硝化反应的研究中,发现C-4和C-6取代基的电子性质与反应性之间存在微妙的相互作用,其中氯,单或双取代的氨基。尽管存在第二个活化基团,诸如在氨基部分上存在芳基或两个烷基之类的影响仍阻碍了反应的进行。
