Five monocyclic and one bicyclic 3-(1-chloroalkyl)-1,2-dioxolanes have been prepared by reaction of alk-3-en-1-yl hydroperoxides with t-butyl hypochlorite in CH2Cl2 in the presence of pyridine or silica; cyclooct-4-en-1-yl hydroperoxide with BuOCl/SiO2 regiospecifically affords 4-chlorocyclooctanone as major product.
在吡啶或CH 2 Cl 2存在下,通过使氢-3-烯-1-基氢过氧化物与次氯酸叔丁酯在CH 2 Cl 2中反应,制备了五个单环和一个双环3-(1-氯烷基)-1,2-二氧戊环。二氧化硅 具有BuOCl / SiO 2的环辛-4-烯-1-基氢过氧化物可以区域特异性地得到4-氯环辛酮作为主要产物。
