3,5-Difluorophenylmagnesium Bromide丨CAS 62351-47-7

3,5-Difluorophenylmagnesium bromide is a Grignard reagent widely used in organic synthesis and pharmaceutical research as a key organometallic intermediate. It is primarily employed for the introduction of the 3,5-difluorophenyl moiety into various carbonyl compounds, such as aldehydes, ketones, and esters, forming secondary and tertiary alcohols or other functionalized aromatic derivatives. This reagent is essential in the synthesis of bioactive molecules, fluorinated pharmaceuticals, agrochemicals, and fine chemicals where the difluorophenyl group modulates chemical, physical, and biological properties. It is also applied in medicinal chemistry for structure–activity relationship (SAR) studies and the construction of complex heterocyclic frameworks.

The benefits of 3,5-Difluorophenylmagnesium bromide stem from its high reactivity, selectivity, and efficiency in forming C–C bonds. The difluorophenyl group contributes to improved metabolic stability, lipophilicity, and electronic properties in drug candidates, enhancing potency and pharmacokinetic profiles. As a Grignard reagent, it allows precise, predictable carbon–carbon bond formation under controlled conditions, facilitating the synthesis of diverse functionalized intermediates. Its compatibility with various solvents and reaction systems provides flexibility for multi-step syntheses, making it a valuable tool in both laboratory and industrial-scale organic synthesis.
