Title Synthesis and design of intramolecular six-coordinate manganese deuteroporphyrins: study of their catalytic activities in oxidation of styrene
Abstract
The thesis based on the model of the natural porphyrins,such as P450, VB12, a series of Mn-deteroporphyrin derivatives introduced in the heme-propionate side chains have been synthesized, and they’ve been employed into the oxidation of styrene as catalyst, which showed different catalytic activity.
The contents of this thesis are presented as follows:
1. The first chapter mainly introduced the history of heme, and elaborated the current situation and mechanism of cytochrome P450 comprehensively. Research on the catalytic oxidation to mimic cytochrome P450 and the catalytic applications of the metalporphyrin has also been carried out. Meanwhile, the technological progress of the catalytic oxidation of styrene has been summarized.
2. The second chapter is the section of experiment. In this chapter, a series of Mn-deuteroporphyrin derivatives have been synthesized and their constructures were proved by MS, 1H NMR, IR and UV-Vis, respectively. In this paper, deuteroporphyrin was synthesized from hemin, and modified the propionate side chains at 13, 17-sites of deuteroporphyrin synthesizing a series of compound, then, these deuteroporphyrin derivatives complexed with manganese ion. At last, these Mn-deuteroporphyrin were used to the process of the oxidation reaction of styrene.
3. The third chapter is the conclusion section. This chapter mainly discussed troubles emeraged in the experiment, optimization of reaction conditions and aftertreatment of the reactions.
Keywords: Hemin, Deuteroporphyrin, oxidation of styrene, metalloporphyrin
