trans-2-(2-Aryl- or heteroarylvinyl)-4,5-dichloropyridazin-3(2H)-ones 3 were synthesized from 4,5-dichloropyridazin-3(2H)-one via 2 step. The photochemical behavior of 3 in THF, methylene chloride, acetonitrile and methanol is dependent on the kind of aryl or heterocyclic ring and the solvent polarity
