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 P2(1)/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.
