Abstract
The new compound 1,2-bis[(2,6-diisopropyl-4-iodophenyl)imino]acenaphthene (I2-dppbian, 1) was synthesized by the condensation of acenaphthenequinone with 2,6-diisopropyl-4-iodoaniline. The reaction of 1 with zinc chloride aff orded the complex [(I2-dpp-bian)ZnCl2] (2) with the neutral diimine ligand. The reaction of 1 with diethyl malonate (DEM) in the presence of copper(I) iodide and cesium carbonate gave 1,2-bis[(2,6-diisopropyl-4-diethylmalonophenyl) imino]acenaphthene (DEM2-dpp-bian, 3). The diamagnetic copper complex [(DEM2-dpp-bian)CuCl] (4) was prepared by the reaction of compound 3 with CuCl. Compounds 1–4 were characterized by elemental analysis, NMR spectroscopy, and IR spectroscopy. The molecular structures of complexes 2 and 4 were determined by single-crystal X-ray diff raction.
