Description

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]arene.
• A rhodium-catalyzed cyclization, converting 1,5-enynes to cyclopentenes and spiro-cyclopentenes.
