Widely used in organic synthesis, this reagent serves as a key nucleophile in carbon-carbon bond-forming reactions. It is particularly valuable in the preparation of substituted aromatic compounds through reactions with electrophilic substrates such as aldehydes, ketones, and esters. It enables the introduction of the 2-chlorophenyl group into target molecules, which is useful in the synthesis of pharmaceuticals, agrochemicals, and functional materials. Due to the presence of the chlorine substituent, the resulting products can undergo further transformations, such as cross-coupling reactions, allowing for sequential functionalization. Its reactivity makes it suitable for use in the construction of complex organic frameworks under controlled anhydrous conditions.
