To develop the convenient and high yield preparation of vanady(4) complexes with tetraphenyporphyrin derivaives,several methods have been examined.For the synthesis of vanady(4) complexes with tetraphenylporphyrin(TPP) and its derivatives having electron-donating groups,the target complexes were arsily obtained by refluxing the corresponding porphyrins and vanadium(3) alkoxide in dimethylacetoamide(DMAc),isolating the crude products with filtrtion from the mixture of the reaction solution and water,and purifying the crude with silica gel chromatograph.The preparation of vanadyl(4)complexes with the TPP derivatives bearing electron withdrawing groups has been successively carried out by reflux of the porphyrin and vanady(4)acetylacetonate in either 1,2,4-trichlorobenzene(TCB)or dimethylsulfoxide(DMSO),removal of the sovent in vacuo,and purification of the crude products with silica gel chromatograph.The vanadyl(4)complexes with anionic TPP derivatives have also been synthesized using vanadyl sulfate and the anionic porphyrins by refluxing in 1,2-glycol.Thecrude products were easiy isolated from the mixture of the reaction solution and excess amounts of acetone,and purified by alumina chromatograph.
