This thesis focuses on oxidation of olefin converting into a series of fundmentalfunctional group compounds. The epoxide and aldehyde were produced in excellentyields by controlling the load of oxidants. Dialcohol and carboxylic acid were alsoafforded via cascade reactions and"one-pot"reactions in moderate yields. Theseconversions from olefins into other functional group compounds are supplements ofolefin chemistry. We studied synthesis and applications of ruthenium porphyrin.Several new fields were developed tentatively based on the large steric hindrance ofporphyrins. Based on the character of phorphyrin as photosensitizer, benzylamineacting as catalyst, synthesis of aldehyde was performed from alkyl halides. The targetproduct was checked, but the yield was low.In chapter 1, we have reviewed the synthesis and application of porphyrin inrecent years.In chapter 2, the synthesis of porphyrin and metal porphyrin were showed indetail. Based on our previous study, porphyrins were further investigated, includingthe affect of purity of 1,2,4-trichlorobenze in preparation of ruthenium porphyrin, thesteric hindrance of porphyrin, and the application as photosensitizer.In chapter 3, a mild oxidation system was investigated to convert olefins into thefundamental organic functional compounds, aldehydes, epoxides, dialcohols, andacids with moderate or excellent yields by controlling the loads of oxidant andreaction procedures. This is the first time describing the conversions between activealkenes and other four kinds of fundamental functional compounds with one catalyticsystem via cascade reactions or"one-pot"reactions.
