Trimethyl borate
Encyclopedia
Trimethyl borate, or boron trimethoxide, has formula B(OCH3)3. It is a clear liquid. It melts at −34 °C and boils at 68-69 °C. It decomposes in contact with water. It is flammable and burns with a green flame.
It is primarily used as a precursor to boronic esters and boronic acid
s for Suzuki couplings.

Boronic acid
A boronic acid is an alkyl or aryl substituted boric acid containing a carbon–boron bond belonging to the larger class of organoboranes. Boronic acids act as Lewis acids. Their unique feature is that they are capable of forming reversible covalent complexes with sugars, amino acids, hydroxamic...
