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.
