| Summary: | 碩士 === 國立中山大學 === 化學研究所 === 86 === This thesis includes two parts. In the first part, we studied the pyrolytic chemistry of 3,4-Dimethyl-thiophene-2,5-dicarbonyl dichloride(67) . We used bromine as the trapping agent and obtained bromobenzene(73), p-bromochlorobenzene(74), p-dibromobenzene(75), and compounds with molecular formulas C5H5ClBr2(76) and C5H4Br4(77) as the main products.In the second part, FVP of 4-methyl benzoyl chloride(42) was performed. When methanol was used as a trapping agent, FVP of 42 gave methyl 4-methylbenzoate(45) as only product. When compound 42 was photolyzed in furan with l=254nm, 3-(4-methylbenzoyl)furan(46) and 2-(4-methylbenzoyl)furan(47) were obtained as the major products.
