Reactions of hydroxyl radicals, generated by photodecomposition of hydrogen peroxide in acetonitrile, with a wide variety of cycloalkenes have been examined. The results show that the major reaction is the addition of hydroxyl radicals to the less substituted end of the double bond, furnishing the secondary alcohols. The reactivity pattern and the observed regio- and stereoselectivity clearly reveal
已经研究了由过氧化氢在乙腈中的光分解产生的羟基自由基与各种环烯烃的反应。结果表明,主要反应是将羟基自由基加到双键取代程度较低的末端,从而提供了仲醇。反应模式和观察到的区域选择性和立体选择性清楚地表明,与底物相关的空间参数在指导加成反应中起主要作用。更重要的是,这项研究导致了一种新的方法的开发,该方法可将烯烃从根本上轻松转化为仲醇,并提供了一些实例,证明了该方法的潜力。
