1,8-Naphthalenediamine reacted with dimethyl and diethyl acetylenedicarboxylates, giving rise to tetrahydronaphtho[1,8-ef]diazepinones (2), dihydroperimidines (3) and bis(enamino)fumarates (4). The relative yields of 3 and 4 depended on the reaction conditions, while products 2 were always very minor. Products 4, the yields of which increased considerably in the presence of a large excess of the acetylenes
