Xie, Haibo; Zhu, Jiangtao; Chen, Zixian; Li, Shan; Wu, Yongming published the artcile< Synthesis of 3-trifluoromethyl-1,4-dihydropyridazines by the PTSA-catalyzed reaction of α,β-unsaturated aldehydes with (E)-1-phenyl-2-(2,2,2-trifluoroethylidene)>, Recommanded Product: 3-(4-Bromophenyl)acrylaldehyde, the main research area is fluoromethyl hydropyridazine preparation PTSA catalyzed condensation unsaturated aldehyde phenylfluoroethylidene.
A facile and efficient method for the synthesis 3-trifluoromethyl-1,4-dihydropyridazine from a variety of readily available α,β-unsaturated aldehyde and (E)-1-phenyl-2-(2,2,2-trifluoroethylidene)hydrazine was developed. The reaction proceeded under mild conditions and gave the expected 1,4-dihydropyridazine products in moderate to high yields.
