【Abstract】 A method for the synthesis of quinolinylporphyrins has been presented. The quinolinylporphyrins were prepared by cyclocondensation of quinolinylcarboxaldehyde with pyrrole in EtCO 2H containing Ac 2O followed by chromatography to remove byproducts.Methylation of iodine by MeI in CHCl 3 give the N-Me derivatives.The products were characterized by IR and element analysis.The Ka 1 and Ka 2 of the reagents have been determined by spectrophotometry. This kind of reagent has high yield and good selectivity for analysis of zinc and copper iore.更多还原
