7-氧杂双环[2,2,1]-庚-2,5-双烯类化合物1去氧后生成取代苯衍生物2,这是一个有趣而又重要的反应.在我们进一步研究取代苯衍生物时,对关键性的去氧反应也作了研究,发现乙酸铜与锌之比较LeGoff法增加3～4倍后制得的锌-铜试剂也可去氧.桥氧化合物3a～c、4和5与锌-铜试剂在四氢呋喃中回流,可得到相应的去氧产物6a～c、7和8. It is an interesting and important reaction that 7-oxabicyclo [2,2,1] -hepta-2,5-diene compound 1 is deoxygenated to form the substituted benzene derivative 2. In our further study on substituted benzene Derivatives, the key deoxygenation reaction has also been studied and found that the copper acetate and zinc compared LeGoff method increased 3 to 4 times the zinc-copper reagent obtained can also be deoxy oxygen bridged 3a ~ c, 4 and 5 are refluxed with zinc-copper reagent in tetrahydrofuran to give the corresponding deoxygenated products 6a-c, 7 and 8.
