3,4-dihydro-2H-benzo[b][1,4]dioxepin-7-ylboronicacid - Introduction

3,4-dihydro-2h-1,-acid is an organic compound with the chemical formula C8H9BO4.

Nature:
-Appearance: Colorless crystalline solid.
-Melting point: About 100-101 ℃.
-Solubility: Soluble in some organic solvents, such as dimethyl sulfoxide (DMSO) and dimethylformamide (DMF).

Use:
3,4-dihydro-2h-1, acid is an Organoboron reagent commonly used in organic synthesis. It can be used as an electron-seeking reagent for halogenated aromatic hydrocarbons, such as the Suzuki coupling reaction reagent for aryl bromides or aryl chlorides. In addition, it can also be used to synthesize other organic compounds, such as catalysts, fluorescent dyes and intermediates in the synthesis of natural products.

Method:
Under normal circumstances, 3,4-dihydro-2h-1, acid can be obtained by chemical synthesis. A common synthetic method is to react p-borobenzaldehyde with indole -7-boronate under appropriate reaction conditions to produce the desired product.

Safety Information:
Under the correct laboratory operation, 3,4-dihydro-2h-1, acid is usually relatively safe. However, because it is a chemical agent, it is still necessary to follow appropriate safety procedures and wear appropriate personal protective equipment (such as gloves and goggles) to prevent contact with skin, eye and inhalation.
