10-羟基-10,9-硼氧杂菲与乙酰基丙酮;1-二茂铁基-1,3-丁二酮,苯甲酰基丙酮,二苯甲酰基甲烷和乙酰基乙酰基苯胺在苯中等摩尔反应生成具色双齿螯合物1、2、3、4和无色分子配合物5.它们的结构由红外光谱、质子核磁共振光谱、质谱及单晶X-射线衍射分析所证实。结果表明:当β-二酮的β-碳原子上连有烷基、茂基(夹心结构)和苯基时,β-二酮通过氧原子与硼配位生成螯合物,这些螯合物因配体骨架π电子的广泛离域而具色,且螯合物的颜色随β-碳原子上苯基和夹心结构的引入而加深.当β-二酮的β-碳原子上连有胺基时,β-二酮通过胺基氮原子与硼键合得到无色分子配合物,并在酰胺端羰基与硼羟基之间存在弱氢键.
10-hydroxy-10,9-b-phenanthroline and acetylacetone; 1-ferrocenyl-1,3-butanedione, benzoyl acetone, dibenzoylmethane and acetoacetylaniline in benzene Moderate molar reaction results in the formation of a bidentate chelate complex 1, 2, 3, 4 and a colorless molecular complex 5. Their structure is confirmed by infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, mass spectrometry and single crystal X-ray diffraction analysis. The results show that β-diketone complexes with boron through the oxygen atom to form chelate when the β-carbon atom of β-diketone has an alkyl group, a mercapto group (sandwich structure) and a phenyl group Ligand backbone π electrons are extensively delocalized and colored, and the chelate color deepens with the introduction of phenyl and sandwich structures on the β-carbon atom. When the β-carbon atom of the β-diketone has an amine group , The β-diketone bonds with boron via amine nitrogen atom to give a colorless molecular complex, and there is a weak hydrogen bond between amide terminal carbonyl group and boronic hydroxyl group.
