Halogen-lithium exchange pilot plant

Another example is a Br-Li exchange reaction of p-dibromobenzene with nBuLi [73]. The reaction is exothermic and requires very low temperature ( — 48 °C) in a batch system. With an integrated microflow system, reaction could be performed at 20 °C followed by reaction with an electrophile at 0°C. [Pg.420]

The use of a microflow system is effective in solving this problem, and a pilot plant for the halogen-lithium exchange reaction of aryl bromides and heteroaryl bromides with butyllithium (Scheme 10.4) has already... [Pg.202]
