Product 1

HCID 7667beta-BromostyreneYield 95%

Procedure

2 g di-t-butyl peroxide were dissolved in 100 g β-bromo ethyl bromo benzene. The mixture was added to the reactor in a manner described in Example 1, together with 25 g methanol and nitrogen at a flow rate of 2 l/h. The reactor was a glass spiral made of a 6 mm wide 5 m long tube heated to 300°-320°C. The products were collected as in Example 1 and consisted of 58 g bromostyrene and 12 g unconverted reactant. The yield was 95% bromostyrene.
