Halogen-lithium exchange reactions under in situ-quench conditions: a powerful concept for organic synthesis.
In contrast to commonly accepted routine protocols for chemical synthesis, the reactions of lithioarenes, generated either by deprotonation or halogen-lithium exchange, need not necessarily be conducted in a stepwise fashion. As this review will demonstrate, the 'in situ-quench protocol provides a powerful alternative to stepwise construction in many cases. The operational simplicity of this methodology suggests interesting applications both for library syntheses and microreactor technology.
