Reactions of (E)-β-nitrostyrenes 1 with triethylaluminum (Et3Al) 2 and alkyl iodide (RI) 3, 4, or 5 in the presence of benzoyl peroxide in diethyl ether solution at room temperature to give 60–100% of the different (E)-alkenes 6, 7, or 8. Under similar conditions, 95% of 1-adamantyl-2-(4-methoxyphenyl)ethene 10 or 80% of 1-(4-oxoadamantyl)-2-(4-methoxyphenyl)ethene 12 also can be easily prepared by
的(反应ë)-β-硝基苯乙烯1用三乙基铝(ET 3 Al)的2和烷基碘(RI)3,4,或5在室温下过氧化苯甲酰在乙醚溶液的存在下,得到60-100%的不同(ë)烯烃6,7,或8。在相似的条件下,也可以通过使用1-轻松制备95%的1-金刚烷基-2-(4-甲氧基苯基)乙烯10或80%的1-(4-氧杂金刚烷基)-2-(4-甲氧基苯基)乙烯12。碘金刚烷9或5-碘-2-金刚烷酮11和2。
