Synthesis and identification of copper (II) complexes using phosphonium salt resulting from the combination of trinylphosphine and ethyl bromoacetate, using stereoscopic methods

Abstract

Phosphonium salts have the general formula and are derived from the sub-ion phosphonium tetrahedral , such as phosphonium iodide . Generally, phosphonium is attributed to an organic derivative, such as tetra-phenyl phosphonium chloride and tetra tetra-methylphosphonium iodide. In this project, the phosphonium compounds [C₂H₅COO (CH₂PPh₃Br)] and its copper (II) complex [C₂H₅COO (CH₂PP₃Br)] [Cu₂Cl₆] were prepared and identified. Phosphonium species were prepared from the reaction of ethyl bromoacetate with terphenylphosphine. Then the final compounds were prepared using the reaction between the phosphonium compound with Na₂ [Cu₂Cl₆]. Then, using spectroscopic methods, preparation of these compounds was investigated.
