General description

Cu is present in +1 (cuprous) valence state in CuCl. CuCl is a semiconductor having a wide band gap. It is a promising candidate for use in silicon-based optoelectronics since its lattice resembles with silicon. It participates in various reactions with Grignard reagents.

Application

Copper(I) chloride (Cuprous chloride, CuCl) has been used to synthesize 7-((tert-butyldimethylsilyl)oxy)hepta-2,4-diyn-1-ol. CuCl may be used in the stereospecific synthesis of cyclic conjugated dienes. It may be employed as a reactant to investigate the stability of copper chloride complexes in hydrothermal solutions.
Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.

A new ligand [C28H20N6O8] (L2) has been synthesized by the condensation reaction of 3-hydroxy-4-nitrobenzaldehydenephenylhydrazine (L1) with diethyloxalate. This ligand L2 is allowed to react with bis(ethylenediamine)Cu(II)/Ni(II)/Zn(II) complexes. It affords [(L2)Cu(en)2]Cl2(1)/[(L2)Ni(en)2]Cl2(2)/[(L2)Zn(en)2]Cl2(3) complexes, respectively. These complexes (1-3) have been characterized by the
