Phenyllithium was allowed to react with the epoxide I under the same experimental conditions. Again, 3, 3-dichloroallyl alcohol was obtained (81% yield). Chlorobenzene was isolated in 68y0 yield. In the above two cases, the halogen-metal interchange reaction must be much faster than the attack of a strongly nucleophilic ion on the epoxide ring, for in each case a halide ion was present from the preparation of the organolithium reagent-bromide ...
