the synthesis of new palladium-oxazoline complexes in one step with good to high yields (68-95%). The oxazolines were prepared from enantiomerically pure alpha-aminoalcohols. The structures of the synthesized palladium complexes were confirmed by NMR, FTIR, TOFMS, UV-visible spectroscopic analysis and X-ray diffraction. The optical properties of the complexes were evaluated by the determination of the
本文描述了一种新的钯-恶唑啉配合物的合成方法,该方法具有良好的收率(68%至95%)。恶唑啉由对映体纯的α-氨基醇制备。合成的钯配合物的结构通过NMR,FTIR,TOFMS,UV-可见光谱分析和X射线衍射确认。通过确定在2.34和3.21eV之间的能隙值(E g)来评估络合物的光学性质。在生态氧化剂(H2O2)存在下,测试了它们的催化活性对Eriochrome Blue Black B(偶氮染料的模型)的降解。脱色的效率已经通过紫外可见光谱分析得到了证实,并且已经研究了影响降解现象的因素。去除铬铬铁合金的收率很高。我们发现,配合物9在5分钟内(C 0 = 30 mg / L,T = 22摄氏度,pH 7,H2O2 = 0.5 mL)促进了84%的消色,并且还确定了能量参数。
