Used as a reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aryl or vinyl halides and boronic acids. Its stability and reactivity profile make it suitable for constructing biaryl compounds, which are common structural motifs in pharmaceuticals, agrochemicals, and functional materials. The trifluoro(3-methylbenzyl)borate anion offers enhanced shelf life and reduced side reactions compared to traditional boronic acids, improving yield and selectivity in coupling processes. It is especially useful in late-stage functionalization of complex molecules where mild reaction conditions are required.
