6,8-Di-tert-butyl-3-(2,4-dimethyl-quinolin-7-yl)-3,4-dihydro-2H-benzo[e][1,3]oxa- zine(1) was obtained by one-pot reaction starting from 2,4-di-tert-butylphenol, 7-amino-2,4- dimethyl-quinoline and paraformaldehyde. The compound was structurally characterized by NMR, IR and single-crystal X-ray diffraction along with the elemental analysis. Compound 1 crystallizes as solvate with chloroform. The solvate 1·CHCl3(C28 H35 Cl3 N2 O, Mr = 521.93) belongs to the triclinic system, space group P1 with a = 10.852(2), b = 11.352(2), c = 13.050(3), α = 101.95(3), β = 92.94(3), γ = 114.64(3)o, V = 1412.4(5)3, Z = 2, Dc = 1.227 g/cm3, F(000) = 552, μ = 0.347 mm–1, R = 0.0959 and wR = 0.2725(I 2?(I)). The chloroform molecule displays a rotational disorder as one chloro atom can be located at two different positions. The packing of 1·CHCl3 was further stabilized by intramolecular C–H···O interactions, intermolecular C–H···N interactions, C–H···π interactions, and π···π interactions. The luminescent properties of compound 1 in both methylene chloride solution and the solid state were studied. 相似文献

合成了一系列带有不同取代基的β-二亚胺配体及其Ni(Ⅱ)的配合物.利用核磁共振谱、元素分析和单晶X射线衍射等手段对配体及配合物进行了表征.元素分析和单晶结构分析表明,在相同的实验条件下苯基取代的β-二亚胺配体锂盐与NiCl2反应只能得到双配体化合物1;而2,6-二甲基苯基及2,6-二异丙基苯基取代的配体锂盐与NiCl2反应得二聚的单氯化物2和3,2个Ni原子通过双氯桥连接在一起.配合物2和3经烷基铝活化后催化乙烯聚合可得到高分子量聚乙烯,活性可达到2.0×105gPE/(molcat·h),分子量最高可达到100万以上. 相似文献
