synthesis, characterization and phosphonium compounds by 1 and 3 bis (chloromethyl) benzene and benzyl bromide and their complexes with mercury

phosphonium salts have the general formula r₄p⁺x^- and are derived from the sub-ion phosphonium tetrahedral (ph⁺₄), such as phosphonium iodide [p(ch₃)⁺₄]^-. generally, phosphonium is attributed to an organic derivative, such as tetra-phenyl phosphonium chloride and tetra tetra-methyl phosphonium iodide. in this project, phosphonium compounds [c₆h₅(ch₂pph₃br)], {c₆h₄-1-(ch₂cl)-3-(ch₂pph₃cl)} and mercury complexes, [c₆h₅(ch₂pph₃)]₂[pd₂cl₂br₂],[c₆h₄-1-(ch₂cl)-3-(ch₂pph₃)]₂[pd₂cl₆] were prepared and characterized. phosphonium salts was prepared from the reaction of 1,3-bis (chloro-methyl)-benzene and tri-phenyl phosphine. then, through the reaction between phosphonium compounds and na₂[pd₂cl₆] final complexes were prepared. next phosphonium salt was prepared from the reaction between benzyl bromide and tri-phenyl phosphine. then, final complexes were prepared through a reaction between phosphonium compounds and na₂[pd₂cl₆].
