Synthesis and characterization of novel thienyl-pyridazine derivatives


We report the synthesis and the photophysical characterization of novel thienylpyridazine derivatives, functionalized in position 3, with different donor groups (thiophene, pyrrole and N,N-dialkylphenylamine). The diazines were synthesized by Suzuki coupling of 3bromo-6-(thiophen-2-yl)pyridazine with commercially available (hetero)aryl-boronic acids in fair to good yields. On the other hand, precursor 3-bromo-6-(thiophen-2-yl)pyridazine was prepared by reaction of a thienyl-pyridazinone with POBr3.
