由于多相性和碱强度的限制，去除水中的卤代烷是非常困难的。我们发现，紫外线（UV）光可以提高消除率的烷基碘，包括伯，仲，叔碘在水中显着的第一次。我们提出了一个串联的自由基-碳正离子反应机制来合理化烷基碘的这种特殊性质。(C)2015爱思唯尔有限公司版权所有。
Elimination of the alkyl halides in water is very difficult due to the heterogeneous nature and the limitation of base strength. We discovered that ultra-violet (UV) light can enhance the elimination rate of alkyl iodides, including primary, secondary, and tertiary iodides in water dramatically for the first time. We propose a tandem radical-carbocation reaction mechanism to rationalize this special property of alkyl iodides. (C) 2015 Elsevier Ltd. All rights reserved.
