Synthesis and photochemical properties of trans-2-(2-aryl- or heteroarylvinyl)-4,5-dichloropyridazin-3(2H)-ones

(Figure Presented) 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.

Substituent-dependence of photophysical properties of trans-2- styrylpyridazin-3(2H)-ones

(Figure Presented) The photophysical behavior of trans-2-styrylpyridazin- 3(2H)-ones 3 strongly depend on the number and the position of substituents in the phenyl ring in THF, methylene chloride, acetonitrile and methanol. The absorption spectra of 3 containing the electron-donating substituents at the para-position show the red-shift, whereas the spectra of 3 containing the electron-withdrawing substituents show the blueshift. For the trans-2-(p-substituted-styryl)pyridazin-3(2H)-ones 3b-3h and 3k-3o, the magnitude of the solvatochromic shifts and the shape of the fluorescence spectra depend on the number and/or the position of substituents in benzene ring. The emission maximum of trans-2-styrylpyridazin-3(2H)-ones involving the electron-donating group is larger than one of trans-2-styrylpyridazin-3(2H)-ones involving the electron-withdrawing group in the phenyl ring. The magnitude of the emission maximum is roughly parallel to the relative electron-withdrawing ability of the substituents of the phenyl ring.
