4,6-Disubstituted pyridazin-3(2H) thiones 3a–f were prepared by thiation of 4,6-disubstituted pyridazin-3(2H)-one 1a–f either with thiourea or phosphorus pentasulphide. The reactivity of 3a-f towards nucleophilic and electrophilic species under different conditions was studied successively. The structure of the products was confirmed by NMR and mass spectral data. Mechanisms for their formation are
4,6-二取代哒嗪-3(2H) 硫酮 3a-f 是通过 4,6-二取代哒嗪-3(2H)-one 1a-f 与硫脲或五硫化二磷硫合制备的。先后研究了 3a-f 在不同条件下对亲核和亲电物种的反应性。产物的结构由NMR和质谱数据证实。还提出了它们的形成机制。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:334–341, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10157
