| Application: | 4-Formylphenylboronic acid is a substrate for Suzuki cross-coupling reactions and it can be used as a reagent for: • Palladium-catalyzed 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. • 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]are • A rhodium-catalyzed cyclization, converting 1,5-enynes to cyclopentenes and spiro-cyclopentenes. |
