A catalytic synthesis of amidines from amides has been established for the first time. The newly developed CO extrusion recombination process takes advantage of an inexpensive nickel(II) catalyst and provides the corresponding amidines with high efficiency. The intramolecular fragment coupling shows excellent chemoselectivity, starts from readily available amides, and provides a valuable alternative
首次建立了由酰胺催化合成synthesis的方法。新开发的CO挤出重组工艺利用了廉价的镍(II)催化剂,并可以高效地提供相应的s。分子内片段偶联显示出优异的化学选择性,从容易获得的酰胺开始,并提供了有价值的alternative合成方案。
