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 R 4 P + X - and are derived from the sub-ion phosphonium tetrahedral (pH + 4 ) , such as phosphonium iodide[p(CH 3 ) + 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 [C 6 H 5 (CH 2 pph 3 Br)], {C 6 H 4 -1- (CH 2 Cl) -3- (CH 2 pph 3 Cl)} and palladium complexes, [ C 6 H 5 (CH 2 pph 3 )] 2 [pd 2 cl 2 Br 2 ], [C 6 H 4 -1- CH 2 Cl) -3-(CH 2 pph 3 )] 2 [pd 2 Cl 6 ] 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 andNa 2 [pd 2 Cl 6 ] 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 Na 2 [pd 2 Cl 6 ].
