m-hydroxybenzonitrile - Reference Information
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Application | 3-hydroxybenzonitrile is an organic intermediate, it can be prepared from 3-cyanophenylboronic acid or 3-hydroxybenzoic acid. |
| preparation | aryl boronic acid (5.0mmol,1.0eq.) povidone-iodine (0.15mmol,0.03eq. Available iodine) and hydrogen peroxide (1.0mL) were added to a 50mL round bottom flask using H2O(2.0mL) as solvent. The reaction mixture was stirred at 25°C under ambient atmosphere. The reaction was monitored by TLC or GC-MS analysis. Once the starting material was consumed completely, the reaction solution was extracted with ethyl acetate (3x 20ml). The mixture was concentrated under reduced pressure. The residue was purified by column chromatography using n-hexane/ethyl acetate gradient elution and concentrated in vacuo to give 3-hydroxybenzonitrile. |
