exo-2-Norbornylzinc bromide solution
exo-2-Norbornylzinc bromide solution (CAS 342029-20-3) is an organozinc halide with the empirical formula C7H11BrZn and a molecular weight of 240.46 g/mol. Supplied as a 0.5 M solution in THF, this reagent is a valuable tool in organic synthesis. It is primarily utilised in cross-coupling reactions and other transformations involving the formation of carbon-carbon bonds, contributing to the construction of complex molecular architectures.
Cross-Coupling Reactions
This organozinc reagent is frequently employed in palladium-catalyzed cross-coupling reactions, such as Negishi couplings, to form new carbon-carbon bonds with various organic electrophiles. It facilitates the efficient synthesis of substituted norbornane derivatives.
Organic Synthesis
exo-2-Norbornylzinc bromide serves as a versatile nucleophile in general organic synthesis. Its reactivity profile allows for controlled functionalisation of organic molecules, enabling the construction of more complex structures.
Organometallic Chemistry
As an organozinc halide, it falls under the category of organometallic reagents, offering specific reactivity patterns distinct from Grignard or organolithium reagents. This makes it suitable for reactions where milder conditions or specific functional group tolerance is required.
