acetylenedicarboxylates with arylidenemalononitriles in the presence of KSCN in MeCN led to a mixture of dialkyl (3E)‐4‐aryl‐3‐(arylideneamino)‐5,5‐dicyanocyclopenta‐1,3‐diene‐1,2‐dicarboxylates and dialkyl 4‐aryl‐5‐cyanothiophene‐2,3‐dicarboxylates. When these reactions were performed in the presence of KCN, only the functionalized 5,5‐dicyanocyclopenta‐1,3‐dienes were obtained.
在KSCN存在下,乙炔基二羧酸二烷基酯与亚芳基丙二腈在MeCN中的反应导致二烷基(3 E)-4-芳基-3-(芳基氨基)-5,5-二氰基环戊-1,3-二烯-1,2的混合物-二羧酸盐和4-芳基-5-氰基噻吩-2,3-二羧酸二烷基酯。当这些反应在KCN存在下进行时,仅获得官能化的5,5-二氰基环戊-1,3-二烯。
