Özet
A concise approach for the construction of ketene aminals and alpha-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 alpha-chlorohydrazones are obtained in good to high yields. In addition, alpha-aminohydrazones are prepared by using alpha-chlorohydrazones as the precursors.
