Description and Uses

3,4,5-Trifluorophenylboronic acid is an arylboronic acid compound used in organic synthesis and as a reaction reagent. It can be used as a catalyst to catalyse the direct amidation of amino acid derivatives and the direct polycondensation of carboxylic acids and amines; it can also be used in the formation of new 1:1 co-crystals with urea C6H4BF3O2-CH4N2O components.

Reactant involved in:

• Preparation of phenylboronic catechol esters and determination of Lewis acidity
• Synthesis of benzopyranone derivatives as GABAA receptor modulators
• Synthesis of multisubstituted olefins and conjugate dienes
• Suzuki cross-coupling reactions
• Preparation of fluorinated aromatic poly(ether-amide)s
