吡唑啉是一类含氮的五元杂环化合物,其化学结构中常连有芳环、杂原子等其它官能团。由于其在农药领域有广泛而重要的作用,长期以来受到业内很多人士的关注。早在19世纪后期,Fischer等人采用丙烯醛与苯肼合成了吡唑啉类化合物,在之后的很长一段时间里,采用α,β-烯酮类(醛)化合物与肼类化合物合成了很多吡唑啉类衍生物。近年以来,随着很多新技术、新方法应用于吡唑啉类化合物的合成之中,出现了很多新型吡唑啉类化合物在农药中的应用,产生了良好的效果。1.除草剂
Pyrazoline is a kind of nitrogen-containing five-membered heterocyclic compounds, the chemical structure often with aromatic rings, heteroatoms and other functional groups. Due to its extensive and important role in the field of pesticides, it has long been the subject of concern in the industry. As early as the late 19th century, Fischer et al. Synthesized pyrazoline compounds using acrolein and phenylhydrazine. For a long time, Fischer et al. Synthesized α, β-enone compounds with hydrazine compounds Many pyrazoline derivatives. In recent years, with many new techniques and new methods applied in the synthesis of pyrazoline compounds, many novel pyrazoline compounds have been used in pesticides and have produced good results.
