Description
Potassium (4-butoxyphenyl)trifluoroborate is a potassium organotrifluoroborate – the tetracoordinate, air-stable counterpart of the corresponding boronic acid, built on a benzene core.
The practical argument for a trifluoroborate is stoichiometric honesty. Boronic acids equilibrate with their cyclic anhydrides (boroxines) and carry variable water, so a weighed sample is of uncertain composition. The trifluoroborate is a defined crystalline salt: it weighs what it is, tolerates air and moisture on the bench, and releases the active boron species only under the hydrolytic conditions of the reaction itself.
Key data
- CAS number: 850623-61-9
- Molecular formula: C10H13BF3KO
- Molecular weight: 256.11 g/mol
- Category: Potassium Trifluoroborates
Typical applications
- multi-step sequences in which the boron handle must survive earlier steps untouched
- reactions run in air, on the open bench, without glovebox handling
- automated and parallel synthesis, where accurate solid dispensing matters
- preparation of fluorinated biphenyls for display-grade liquid crystal blends
- Suzuki-Miyaura coupling where a weighable, non-hygroscopic boron source is required
