A Three-Component One-Pot Synthesis of Functionalized 5,5-Dicyanocyclopenta-1,3-dienes from Arylidenemalononitriles, Activated Acetylenes, and KCN or KSCN
[摘要]：The reaction of dialkyl 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
