| Abstract: | In this paper,experimental method of electrochemistry and spectroelectrochemistry are used to investigate the synthetic condition of coenzyme B12 model compounds,and then a series of water soluble axial benzyl group cobalt porphyrins RPhCH_2-CoTMAPI is synthesized by chemical method,where R=CH_(3~-),NO_(2~-),H-,Br-,KCO_(2~-),and CoTMAPI is taken as (4-trimethylanilino)cobalt porphine iodide.These compounds are characterized by IR and UV spectra.The electronic effect of axial groups on the Co-C bond is discussed by quantum
chemical CNDO/2 method. |
