| Summary: | 碩士 === 臺北市立教育大學 === 自然科學系碩士班 === 99 === This study on the synthesis of 5-aryl-4,4-dimethoxy-2-cyclohexeones that 4,4-dimethoxy-2,5-cyclohex-di-enones be chelated carbonyl group by Lewis acid, MAD [methyl aluminium bis(2,6-di-tert-butyl-4-methyl
phenoxide)],and then executed 1,4-addition with prepared aryl grignard reagent, prepare as 0.01 M in trifluoroacetic ethanol respectively and carry out photochemistry reaction using 350 nm wavelength light. The results show that aromatic group is toluene causing the main skeleton of product is cyclopentanone on the other hand that aromatic group is thiophene causing the main skeleton of product is cyclobutanone.
