Bromine-Magnesium Exchange of Aryl Bromides

The bromine-magnesium exchange of aryl bromides proceeds on treatment with BUjMgl.i at O C. Representative examples are shown in Tab. 3.13. [Pg.113]

Polyfunctional aryl bromides, bearing a chelating function ortho to bromine readily undergo a bromine-magnesium exchange.39,40 40a Even the less effective methoxy group directs the substitution in the case of 2,4-dibromoanisole (Scheme 14).41... [Pg.36]
