【摘要】 <正> 多卤代烃在有机反应机理和结构研究中有着重要意义,作为一个有用的合成中间体,其制备也受到人们重视。我们在此报道二氯亚甲基环已烷(1)与氯及溴的反应和其它有关反应的实验结果。 1 于氯作用,主要得到加成产物1—氯—1—更多还原

【Abstract】 Besides addition product 2-halo-substiituted dichloromethylenecyclohexane by-produ-cts were produced from the reactions of the titled compound with chlorine and bromine. Toprepare the compound 1-trichloromethylcyclohexene by a series of elimination reactions wasunsuccessful. The axial conformer of 2-substituted dichloromethylenecyclohexane has beenobserved, which was interpreted in terms of anomeric effect.更多还原
