Synthesis and characterization of palladium complexes in combination with Phosphonium salts of 1,3-bis (chloro-methyl)-benzene and benzyl bromide by using stereoscopy methods

Abstract

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 palladium 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 andNa2[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].
