3-Pyrrolinediimines by the Reaction of Perchlorobutenyne with Primary Aromatic Amines

The reaction of perchlorobutenyne (1) with primary aromatic amines in THF or DMF leads to the chlorine-free title compounds 12.The structure of 12a is proven by X-ray structure analysis.As intermediates in the reaction 1 -> 12 appear the ketenimines 3, wh
