| | 4-Formylphenylboronic acid Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powder | | Uses | suzuki reaction | | Uses | 4-Formylbenzeneboronic acid acts as a reagent used for Palladium-catalyzed arylation Suzuki-Miyaura cross-coupling in water, copper-mediated ligandless aerobic fluoroalkylation of arylboronic acids with fluoroalkyl iodides, ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids, triethylamine-catalyzed three-component Hantzsch condensations, copper-catalyzed nitrations, oxidative mono-cleavage of dialkenes catalyzed by Trametes hirsuta, palladacycle-catalyzed cross-coupling of arylboronic acids with carboxylic anhydrides or acyl chlorides, palladium-catalyzed aerobic oxidative cross-coupling reactions. It acts as a reagent used in preparation of sensitizers with dithiafulvenyl unit as electron donor for high-efficiency dye-sensitized solar cells, a novel protein synthesis inhibitor active against Gram-positive bacteria. | | Uses | 4-Formylphenylboronic acid is a substrate for Suzuki cross-coupling reactions and it can be used as a reagent for:

- Oxidative mono-cleavage of dialkenes catalyzed by Trametes hirsuta.
- Palladacycle-catalyzed cross-coupling of arylboronic acids with carboxylic anhydrides or acyl chlorides.
- Palladium-catalyzed aerobic oxidative cross-coupling reactions.
- The synthesis of sensitizers with dithiafulvenyl unit as electron donor for high-efficiency dye-sensitized solar cells.
- The synthesis of a novel protein synthesis inhibitor active against Gram-positive bacteria.
- The Suzuki aryl-aryl coupling of the upper rim of hexahomotrioxacalix[3]arene.
- A rhodium-catalyzed cyclization, converting 1,5-enynes to cyclopentenes and spiro-cyclopentenes.
| | Flammability and Explosibility | Not classified | | Synthesis | Potassium phenyltrifluoroborate (184 mg, 1.00 mmol) was added to a solution of iron trichloride (185 mg, 1.10 mmol) in 3 mL of 1:1 THF/water. The mixture was stirred at room temperature for 30 min. The reaction mixture was then passed through a short column containing neutral absorption alumina. The alumina was then washed with a mixture of ethyl acetate/hexanes (2:1) to obtain 4-Formylphenylboronic acid (105 mg, 86%). [The boronic acid products can also be isolated by simple extraction techniques.] |
