The model compounds of androgenic steroid-bismetallopor-phyrins 3a-3d and androgenic monometalloporphyrins 2a-2d have been synthesized. Catalytic study in two-phase condition on epoxidation of styrene under the catalysis of model catalysts shows (hat the catalytic performances of steriod-bismet-alloporphyrin is superior to steroid- metalloporphyrin and the corresponding simple metalloporphyrin. The excellent catalytic property of steriod-bismetallopotphyrin can be rationalized as the hydrophobic action of steroid framework and the cooperative action of two metalloporphyrins in catalysis. 相似文献
