The title compound 5,5-dimethyl-2-(4-chlorophenyl)(3-hydroxy-5,5-dimethyl-2-cyclohexen-1-one-2-yl)methyl-3-(4-methoxyphenylamino)-2-cyclohexen-1-one has been synthesized,and its crystal structure was characterized by X-ray single-crystal diffraction. The crystal belongs to monoclinic,space group P21/c with a=9.4193(13),b=26.915(4),c=21.188(3),β =101.906(3)°,V =5256.2(13)3,Z =4,C60H68Cl2N2O8,Mr=1016.06,Dc=1.284 g/cm3,F(000)=2160,λ(MoKα)=0.71073,μ=0.182 mm–1,R=0.0530 and wR=0.1131 for 4128 observed reflections (I>2σ(I)). X-ray analysis reveals that there are two independent molecules in the unit and the cyclohexenone rings adopt different conformations. In addition,there are four intramolecular hydrogen bonds in the title molecule. 相似文献

Three novel and simple N,N'-diacylhydrazine-based colorimetric receptors have been prepared. The binding properties of the receptors to anions such as F^-, Cl^-, Br^-, AcO^-, HSO4^- and HEPO4^- in acetonitrile solution were examined by UV-Vis spectroscopy methods, which show high sensitivity and selectivity to F^- and AcO^- over other anions. The results indicated that a 1 : 1 stoichiometry complex was formed between the receptors and the anions, while ^1H NMR titrations confirmed hydrogen binding interaction between the receptors and the anions. 相似文献

1 INTRODUCTION -Thiocarbonylthioformamide synthesized in 1980[1, 2] is a class of stable and almost unexplored compounds[3]. We have reported the reaction of - thiocarbonylthioformamides in our previous paper[4]. Here, we will report a novel synthesis of 2 by the reaction of 1 and trimethyl phosphite in refluxing xylene. In order to determine the structure of 2, X- ray crystallographic study was carried out. 2 EXPERIMENTAL 2. 1 Preparation of the title compound Trimethyl phosph… 相似文献
