Mono and di-halobenzenes and alkoxide ions gave monoalkoxybenzenes, but no phenols, when catalyzed by high molecular weight poly (ethylene glycol) s as phase transfer catalysts. Bromobenzenes were more reactive than chlorobenzenes but gave more side products, and for alcohols the reactivity was primary> secondary> tertiary.
