Reaction of Imines with Naphthoquinones and 2-(Dicyanomethylene)-1,3-indandione

Benzylideneanilines react with 2,3-dichloro-1,4-naphthoquinone and 2,3-dicyano-1,4-naphthoquinone to give 2-arylamino-3-chloro-1,4-naphthoquinones and 2-arylamino-3-cyano-1,4-naphthoquinones respectively together with the corresponding aldehydes.Similarly benzylideneanilines react with 2-(dicyanomethylene)-1,3-indandione to give 2-arylamino-2-(1,3-dioxo-2-indanylidene)acetonitriles.
