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 phosphoruspentasulphide. 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
