A concise approach for the construction of ketene aminals and α-chlorohydrazones has been developed. It involves reactions of the regiodefined gem-dihalo nitrovinyl compound of in situ generated imide chlorides in different media with primary arylamines being dependent on the aryl groups. A range of ketene aminals and α-chlorohydrazones are obtained in good to high yields. In addition, α-aminohydrazones
已经开发了用于构造乙烯酮缩醛和α-氯hydr的简明方法。它涉及在不同介质中原位生成的酰亚胺氯化物的区域定义的宝石-二卤代硝基乙烯基化合物与伯芳基胺的反应,该伯芳基胺取决于芳基。以良好或高收率获得了一系列的乙烯酮缩醛和α-氯nes。另外,通过使用α-氯hydr酮作为前体制备α-氨基hydr。
