Nature:
-Appearance: colorless liquid
-Molecular formula: C11H21BO2
-Molecular weight: 194.09g/mol
-Melting point:-5 ℃
-Boiling point: 80-85 ℃
-Density: 0.889 g/mL
-Solubility: Soluble in organic solvents such as ethanol, methanol and dichloromethane
Use:
3,3-dimethylallboronic acid pinacol ester, 2-(3-Methyl-but-2-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is mainly used for the cross-coupling reaction of halogenated olefins in organic synthesis, in particular, the palladium-catalyzed Suzuki coupling reaction.
