4,4,5,5-Tetramethyl-2-(3-methylbut-2-en-1-yl)-1,3,2-dioxaborolane - Introduction
3,3-dimethylallboronic acid pinacol ester, 2-(3-Methyl-but-2-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, also known as 3,3-dimethylallboronic acid pinacol ester or 2-(3-methyl-but-2-butl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, is an organic compound.
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. It can be introduced into other organic molecules as an inoculant group for the construction of complex organic compounds.
Method:
The preparation of 3,3-dimethylallylboronic acid pinacol ester, 2-(3-Methyl-but-2-enyl)-4,4, 5,5-tetrameyl-1, 3,2-dioxaborolane can be carried out by the following steps:
1. 3-Chloro-2-butene (3-chloroo-2-butene) reacts with triethylamine to generate 3-Methyl-2-butene (3-Methyl-2-butene).
2. The resulting 3-methyl-2-butene was reacted with Pinacolborane or Diboron ester to give 3,3-dimethylallylboronic acid pinacol ester, 2-(3-Methyl-but-2-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.
Safety Information:
3,3-dimethylallylboronic acid pinacol ester, 2-(3-Methyl-but-2-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane has low toxicity, but it is still necessary to pay attention to safe operation. During handling and use, the laboratory's safe operating procedures should be followed and appropriate protective measures should be taken, such as wearing protective glasses and gloves. Avoid skin contact and inhalation. If inadvertent contact or misuse, should be promptly washed or seek medical assistance.
