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 [C 2 H 5 COO (CH 2 PPh 3 Br)] and its copper (II) complex [C 2 H 5 COO (CH 2 PP 3 Br)] [Cu 2 Cl 6 ] 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 Na 2 [Cu 2 Cl 6 ]. Then, using spectroscopic methods, preparation of these compounds was investigated.
