This chemical is primarily used in organic synthesis as a reagent for introducing the 2-chlorobenzyl group into various molecules. It is particularly valuable in cross-coupling reactions, such as Negishi coupling, where it facilitates the formation of carbon-carbon bonds. This allows for the construction of complex organic compounds, including pharmaceuticals, agrochemicals, and fine chemicals. Its reactivity with electrophiles makes it a versatile tool in the synthesis of aromatic compounds and heterocycles. Additionally, it is employed in the modification of polymers and materials to impart specific functional properties.
