一种1,10菲啰啉-5,6-二酮及其单肟的高效合成方法 总被引:2,自引:0,他引:2
1,10菲啰啉5,6二酮(2)与1,10菲啰啉5,6二酮单肟(3)作为稠杂环共轭配体,既具有良好的配位特性,又是重要的有机合成反应中间体。由化合物2和它的衍生物与金属离子形成的配合物可以用于抗肿瘤药物、DNA探针、非线性光学材料、超分子组装分子骨架、自旋交叉配合物等许多领域。化合物3则用于有机光致变色化合物螺噁嗪的合成。化合物2无法直接用氧化剂氧化1,10菲啰啉(1)得到。它最初是从化合物1用混酸硝化制备5硝基1,10菲啰啉的废水中分离得到的,产率1%。Amouyal等[1]改进此方法,将产率提高到20%。随着应用研究的需求,对它的合成研究一直没有间… 相似文献

合成了不同邻菲啰啉(phen)含量的聚(苯乙烯-丙烯酸)载体铁邻菲啰啉配合物(SAAC·Fe·phen)和不同5-硝基邻菲啰啉(Nphen)含量的聚(苯乙烯-丙烯酸)载体铁5-硝基邻菲啰啉配合物(SAAC·Fe·Nphen)。元素分析和红外结果证明SAAC·Fe·phen具有下面的结构:SAAC·Fe·phen-(i-Bu)_3Al二元体系的催化效率是SAAC·Fe-phen-(i-Bu)_3Al三元体系的2倍,是小分子铁的400倍。在SAAC·Fe·phen和SAAC·Fe·Nphen体系中,当phen(或N pnen)/Fe的摩尔比为0.7左右时催化活性最高。催化活性随着Al/Fe摩尔比的增大而升高,但当Al/Fe摩尔比大于70以上活性趋于恒定,和小分子铁催化荆相比这种高分子铁催化剂可以提高聚合温度。 相似文献

设计合成了2个1,10-邻菲啰啉并咪唑衍生物阴离子受体2-(2-羟基苯基)-1H-咪唑[4,5-f][1,10]邻菲啰啉(1)和2-(2-羟基-5-溴苯基)-1H-咪唑[4,5-f][1,10]邻菲啰啉(2), 受体2的结构由X射线单晶衍射分析确证. 通过紫外-可见光谱滴定及 1H NMR滴定研究了这2个受体对F-, Cl-, Br-, I-, H2PO4-和AcO- 6种阴离子的识别传感作用及作用机理. 结果表明, 受体对AcO-, F-和H2PO4-有较强的传感作用, 溶液颜色由淡黄色变为黄色; 对Cl-的作用较弱; 而对Br-和I-则无明显作用. 通过机理研究发现, 受体与F-, H2PO4-和AcO-形成1: 1的氢键超分子, 当阴离子的量超过受体的1倍以后, 咪唑氮上的氢转移到阴离子; 受体与Cl-以氢键形成超分子复合物, 而与Br-和I-作用很弱. 相似文献

Isoindole or 1H-isoindole, where there is the possibility of tautoinerism, is too unstable to be isolated, and its existence is ascertained only by Diels-Alder addition products with maleic anhydride and N-phenylmaleinimide.1) Moreover, the systematic preparations of isoindole derivatives have not been confirmed.2) However, several successful isoindole syntheses have been realized from ortho-disubstituted benzene derivatives. For instance,3) catalytic reduction over Raney nickel of o-cyanobenzophenone gave 1-phenylisoindole, accompanied by the oxidative coupling product. We wish to report now a synthesis of an isoindole derivative (2) by the dimerization of o-tolunitrile and several reactions of the compound (2), and the physical data were also reported. 相似文献

A novel triphenylamine derivative of 4, 4‘-bis-[2-[4-[N,N-bis-(4-methoxyphenyl-amino)] phenyl-l-yl]-viny1-1-y1]-1, 1‘-biphenyl (DMPAVBI) was synthesized. The chemical structure was confirmed by IR, ^1H NMR spectroscopy and elemental analysis. Its properties were studied by UV-Vis spectroscopy, photoluminescence spectroscopy and cyclic voltammetry methods. 相似文献

The synthesis of an optically active hemiporphyrazine with chiral binaphthyl substituents ( 1 ) is reported, providing the first example of the incorporation of an intrinsically chiral moiety into the macrocyclic core of a hemiporphyrazine analogue. A negative circular dichroism (CD) signal is observed in the 325–450 nm region of the CD spectrum of (S,S)‐ 1 , while mainly positive bands are observed in the 220–325 nm region. Mirror symmetry is observed across the entire wavelength range of the CD spectra of (R,R)‐ 1 and (S,S)‐ 1 . An irreversible one‐electron oxidation wave with an onset potential at 1.07 V is observed by cyclic voltammetry, along with a reversible one‐electron reduction wave at ?0.85 V. Density functional calculations reproduce the experimentally observed data and trends, and provide further insight into the nature of the electronic transitions. 相似文献
