Used as a highly reactive organometallic reagent in organic synthesis, particularly in cross-coupling reactions and nucleophilic additions. Its enhanced solubility and stability in the presence of lithium chloride make it effective for deprotonation of weakly acidic substrates and for generating carbanions in a controlled manner. Commonly employed in the synthesis of complex organic molecules, including pharmaceuticals and fine chemicals, where selective carbon-carbon bond formation is required. Also utilized in directed ortho-metalation strategies when working with aromatic systems bearing directing groups.
