2-Nitrophenylboronic acid Chemical Properties,Usage,Production
Chemical Properties
White to orange to brown solid
Uses
Boronic acid catalyst used for:
- Mild and selective dipolar cycloadditions of unsaturated carboxylic acids with azides
- Transposition of allylic alcohols and Meyer-Schuster rearrangements
Reactant involved in:
- Suzuki-Miyaura cross-coupling reactions with aryl halides or nitroarenediazonium tetrafluoroborates
- Copper-catalyzed halogenation
- Oxidative arylation of aminopyrazolyl disulfides
Synthesis
98-80-6
5570-19-4
Using phenylboronic acid as starting material, nitric acid (126 g, 2 mol) and sodium nitrite (0.04 mol) were added dropwise to the reaction system and the reaction temperature was controlled at 45 °C. The reaction mixture was reacted with dimethylformamide (15 mol) under stirring conditions. Upon completion of the reaction, the mixture was poured completely into ice water, concentrated to a small volume, cooled and allowed to stand until a solid precipitate precipitated. The solid was separated by filtration and washed with ice water, and the final product 2-nitrophenylboronic acid 165.3 g was collected in 99.0% molar yield and >99.5% HPLC purity.
