While in option (d) halogen replaces the hydrogen of the benzene halogen. Metal–halogen exchange is a basic reaction in organometallic chemistry that transforms an organic halide into an organometallic product.
Electropositive metals. Halophilir attacks on C-X bonds (X= Br, Cl) by a base can easily initiate intermolecular brominechlorine exchange reactions either among bromine- or chlori.
Halogen Exchange Reaction of Aliphatic Fluorine Compounds with Organic Halides as Halogen Source
The reaction should only require 1 eq of BuLi if the temperature is low enough. Metal-halogen exchange reactions are extremely fast even at exchange. A mixture of (i) finely-divided alkali link fluoride (e.g., KF), (ii) exchange compound having at least one halogen atom of atomic number greater than.
