and hydrazone moieties were synthesized and their molecular structures were confirmed by IR, 1H, 13C NMR spectroscopy and mass spectrometry data. X-ray analysis of 2,2'-[[[(p-tolylazanediyl)bis(ethane-2,1-diyl)]bis(4-phenyl-4H-1,2,4-triazole-5,3-diyl)]bis(sulfanediyl)]bis[1-(p-tolyl)ethan-1-one] crystal has revealed, that the molecules in the crystal are associated by means of intermolecular hydrogen
合成了一系列带有双组氨基硫脲、恶二唑硫酮、不同N-和S-取代的三唑硫酮、吡咯和腙部分的新型3,3'-(对甲苯氮烷二基)二(丙酰肼)衍生物,并通过以下方法证实了它们的分子结构:IR、1 H、13 C NMR 光谱和质谱数据。2,2'-[[[(对甲苯氮烷二基)双(乙烷-2,1-二基)]双(4-苯基-4 H -1,2,4-三唑-5,3-)的X射线分析二基)]双(硫基)]双[1-( p(-tolyl)ethan-1-one]晶体表明,晶体中的分子通过OH·N型分子间氢键缔合,形成中心对称二聚体。通过DPPH自由基清除测定、还原力测定和铁还原抗氧化力测定来筛选合成化合物的抗氧化活性。在合成的化合物中,2,2'-[3,3'-(对甲苯氮烷二基)双(丙酰基)]双( N-苯肼-1-硫代甲酰胺)被认为具有最高的抗氧化活性,其抗氧化活性为1.25–比商业抗氧化剂丁基羟基甲苯高2倍。 图形概要
