Potassium trifluoro(neopentyl)borate is an organoboron reagent widely used in organic synthesis, particularly as a stable nucleophilic partner in cross-coupling reactions such as the Suzuki-Miyaura coupling. This reaction facilitates the formation of carbon-carbon bonds, making it essential for constructing complex molecules in pharmaceutical and fine chemical production. The trifluoroborate moiety enhances stability under aqueous and mild conditions, reducing side reactions and improving yields compared to traditional boronic acids. It is also utilized in borylation processes to introduce alkyl groups and as an intermediate in the synthesis of advanced materials.
