Polyethylene glycol(PEG) is used as a phase transfer catalyst in the bromo-hydroxylation of styrene.Experimental results showed that the yield of β-blomo-α-hydroxyethylbenzene and the reaction rate are enhanced by addition of PEG into the system, and the effect increased remarkably with the increasing amount of sulfuric acid. The maximum, yield of β-bromo-α-hydroxyethylbenzen is 92%. A possible mechanism is proposed.
- phase transfer catalysis,
- polyethylene glycol,
