pyrazolinones 5a, b and 12a, b to afford different products 8, 9, 10, 11, and 14a, b – depending on the substitution in the pyrazole ring. Compound 1a reacts also with the pyridazinone derivative 15 to afford the phthalazinone 16, and with the thiazolinones 17a–c to afford the pyrano[2,3‐d]thiazoles 20a–c, respectively. It reacts also with the malononitrile dimer 21a and with ethyl cyanoacetate dimer 21b
2-(5-氯-1,3-二苯基-1H-吡唑-4-基亚甲基)-丙二腈1a与丙二腈2a-d的亚芳基反应,分别得到三芳基-5-氯吡唑3a-d。1a 与活性亚甲基吡唑啉酮 5a、b 和 12a、b 反应得到不同的产物 8、9、10、11 和 14a、b,这取决于吡唑环中的取代。化合物 1a 还与哒嗪酮衍生物 15 反应生成酞嗪酮 16,并与噻唑啉酮 17a-c 反应生成吡喃并 [2,3-d] 噻唑 20a-c。它还与丙二腈二聚体 21a 和氰基乙酸乙酯二聚体 21b 反应,分别生成吡唑基吡啶 22a、b。合成的化合物对 Biomphalaria alexandrina 蜗牛显示出中等的杀软体动物活性。
