CYCLIZATION REACTIONS OF NITRILES. III. SYNTHESIS OF o-CYANOANILINES BY THE THORPE REACTION
The reaction of alkylidenemalononitriles with arylidene derivatives of malononitrile and cyanoacetic ester leads to the formation of derivatives of 1-amino-2,6-dicyano-3,5-diaryl-1,3-cyclohexadiene or 2,4-dicyano-3-amino-5-arylbicyclodeca-2,10-dien
