Propylzinc bromide solution
Propylzinc bromide solution (CAS: 156567-57-6), with the linear formula CH3CH2CH2ZnBr and a molecular weight of 188.38 g/mol, is an organozinc halide reagent. Supplied as a 0.5 M solution in Tetrahydrofuran (THF), this compound is highly flammable and can form explosive peroxides. It is primarily utilised as a versatile building block in organic synthesis, particularly for the formation of carbon-carbon bonds and in cross-coupling reactions.
Organic Synthesis Intermediate
Propylzinc bromide is extensively employed in the construction of complex organic molecules. Its organometallic nature facilitates carbon-carbon bond formation through reactions such as Negishi coupling.
Cross-Coupling Reactions
This reagent serves as a key component in various transition-metal catalysed cross-coupling reactions, enabling the introduction of a propyl group onto diverse organic scaffolds.
Preparation of Organometallic Compounds
It acts as a precursor for synthesising other organozinc derivatives and organometallic compounds, expanding its utility in advanced chemical transformations.
