Abstract: The synthesis of three kinds of bismetalloporphyrins was reviewed：the commonly used and mature synthesis methods of covalent flexible single bond linked bismetalloporphyrins； series cross coupling methods and other methods used to synthesize conjugated group linked or directly linked bismetalloporphyrins；synthetic methods of m-oxo-bismetalloporphyrins. Homogeneous catalytic oxidations of organic substrates such as alkane and alkene catalyzed by m-oxo-bismetalloporphyrins and flexible alkoxyl oxygen linked-bismetalloporphyrins were introduced，and the catalytic mechanism of these two bismetalloporphyrins，along with the possible synergetic catalysis mechanism of binuclear central metal were discussed. Finally，the research prospects of bismetalloporphyrins as biomimetic catalysts were summarized.
