Cyclohexylzinc bromide is primarily used in organic synthesis as a reagent for the introduction of the cyclohexyl group into various organic compounds. It is particularly valuable in transition-metal-catalyzed cross-coupling reactions, such as Negishi coupling, where it facilitates the formation of carbon-carbon bonds. This reagent is often employed in the synthesis of complex molecules, including pharmaceuticals and agrochemicals, due to its ability to selectively transfer the cyclohexyl moiety to electrophilic partners. Additionally, it is utilized in the preparation of organometallic intermediates that are further transformed into target molecules in medicinal chemistry and materials science. Its reactivity and stability make it a preferred choice for precise and efficient synthetic transformations.
