Borate Esters
Borate Esters
Borate esters are alkyl or aryl organic compounds of the type B(OR)3, and are precursors for the boric acid derivatives. Trimethyl borate is used as a precursor to boronic esters for Suzuki couplings. It is used as a solvent or a catalyst for the production of resins, waxes, paints, varnishes. It is also used as a methylation agent and a boron source in organic reaction to manufacture biocides, flame retardants for textile, in welding fluxes, anti-oxidants, corrosion inhibitors, tackifiers for elastomers and rubbers, cross-linking agents for polymers, dehydrating agents and plastic stabilizers. Direct amidation of carboxylic acids and transamidation of primary amides can be achieved with borate esters.
