Potassium sec-butyltrifluoroborate
Potassium sec-butyltrifluoroborate (CAS: 958449-00-8; Formula: C4H9BF3K; Molar Mass: 164.02 g/mol) is a stable organotrifluoroborate salt. It serves as a valuable reagent in organic synthesis, particularly for the direct alkylation of heteroaryls and in Suzuki cross-coupling reactions. Its robust nature makes it a reliable alternative to traditional boronic acids in various synthetic transformations.
Suzuki Cross-Coupling Reactions
Potassium sec-butyltrifluoroborate is employed as a coupling partner in Suzuki reactions, facilitating the formation of carbon-carbon bonds. This enables the synthesis of complex organic molecules, including pharmaceuticals and advanced materials.
Direct Alkylation of Heteroaryls
This organotrifluoroborate salt is effective for the direct alkylation of heteroaromatic compounds. This application is crucial for introducing sec-butyl groups onto various heterocyclic scaffolds in a regioselective manner.
Boronic Acid Surrogate
As a stable and versatile surrogate for boronic acids, potassium sec-butyltrifluoroborate offers advantages in handling and reactivity. It participates readily in a range of cross-coupling and functionalisation reactions.
