Abstract

The CuCl-catalyzed olefination with CCl₄ in the presence of tetramethylethylenediamine in DMSO leads to the formation of (E)-1-(4-bromo-(2,2-dichloro-1-(4-fluorophenyl)vinyl)-diazene from (E)-1-(4-bromophenyl)-2-(4-fluorobenzylidene)hydrazine. The structure was confirmed by conventional spectroscopy techniques (nuclear magnetic resonance, electrospray ionization mass spectrometry) and determined by X-ray diffraction analysis of single crystals. The title compound crystallized in a monoclinic cell (space group P2₁/c, Z = 4) with a centrosymmetric arrangement of molecules in the crystal structure, showing interesting non-covalent interactions that were studied by Hirshfeld surface analysis.

（E）-1-（4-溴苯基）-2-（2,2-二氯-1-（4-氟苯基）乙烯基）二烯的晶体结构和Hirshfeld表面分析

摘要

在四甲基乙二胺在DMSO中存在下，用CCl ₄进行CuCl催化的烯烃化反应会导致从中形成（E）-1-（4-溴-（2,2-二氯-1-（4-氟苯基）乙烯基）-二氮烯（E）-1-（4-溴苯基）-2-（4-氟亚苄基）肼的结构通过常规光谱技术（核磁共振，电喷雾电离质谱）确定，并通过单晶的X射线衍射分析确定。标题化合物在单斜晶胞（空间群P 2 ₁ / c，Z = 4）具有晶体结构中分子的中心对称排列，显示出有趣的非共价相互作用，这是通过Hirshfeld表面分析研究的。
