Is a phase transfer catalyst really needed for gem-dihalocyclopropanation of alkenes with haloforms in the presence of alkali metal hydroxide?

Chloroform, bromoform and dibromochloromethane react with alkenes in the presence of cone. aq. sodium hydroxide, without phase-transfer catalyst, giving gem-dihalocyclopropanes. The process is particularly useful for preparation of gem-bromochlorocyclopropanes which are formed in good yields and in high selectivity.
