以6-(4-甲基-3-戊烯基)萘-1,4-二醌为原料,过氧乙酸为氧化剂,通过环氧化反应制备了目标产物6-(2-(3,3-二甲基噁丙环-2-基)乙基)萘-1,4-二酮。产物结构通过1H-NMR、FT-IR和GC-MS分析得到表征和确定。探讨了反应底物、氧化剂以及碳酸氢钠的比例、溶剂、温度、时间等对反应转化率和得率的影响,得到优化工艺条件为:萘二醌、过氧乙酸和碳酸氢钠摩尔质量比为1∶3∶12,以氯仿为反应溶剂,反应温度30℃,反应时间5 h。在此优化条件下,可得到目标产物6-(2-(3,3-二甲基噁丙环-2-基)乙基)萘-1,4-二酮的得率为907%。
Using 6- (4-methyl-3-pentenyl) naphthalene-1,4-diquinone as starting material and peracetic acid as oxidant, the target product 6- (2- Dimethyloxan-2-yl) ethyl) naphthalene-1,4-dione. The product structure was characterized and confirmed by1H-NMR, FT-IR and GC-MS analyzes. The effects of the ratio of the reaction substrate, oxidant and sodium bicarbonate, solvent, temperature and time on the conversion and yield of the reaction were investigated. The optimum technological conditions were as follows: molar ratio of naphthoquinone, peracetic acid and sodium bicarbonate 1: 3: 12, chloroform as reaction solvent, reaction temperature 30 ℃, reaction time 5 h. Under this optimal condition, the yield of the target product 6- (2- (3,3-dimethylpropan-2-yl) ethyl) naphthalene-1,4-dione is 907%.
