  Selective mono-amination of dichlorodiazines

  摘要：

  A mild, easy-to-perform, and versatile method for the formation of aminochlorodiazines from reaction of several types of dichlorodiazines (i.e., pyridazines, pyrimidines, and pyrazines) with primary or secondary amines in ethanol in the presence of triethylamine as a base, is described. The methodology is general and efficient despite noticeable difference in reactivity between diazines. While dichloropyridazine and dichloropyrazine require several hours of heating at reflux for the reaction to proceed, dichloropyrimidines reach completion within minutes at room temperature.

  A range of novel 4-amino-6-arylpyrimidines has been prepared under mild conditions by an electrochemical reductive cross-coupling between 4-amino-6-chloro-pyrimidines and functionalized aryl halides. The process, which employs a sacrificial iron anode in conjunction with a nickel(II) catalyst, allows the formation of coupling products in moderate to high yields.
