Application
4-Cyanophenylboronic acid can be used as a reactant in:
It can also be used to prepare:
- Palladium-catalyzed Suzuki-Miyaura cross-coupling in water.
- Ruthenium catalyzed direct arylation of benzylic sp3 carbons of acyclic amines with arylboronates.
- Ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids.
- Ferric perchlorate-promoted reaction of fullerenes with various arylboronic acids to give fullerenyl boronic esters.
- Phosphine-free Suzuki-Miyaura cross-coupling.
- Palladacycles as effective catalysts for multicomponent reaction with allylpalladium-intermediates.
- Chan-Lam-type Cu-catalyzed S-arylation of thiols.
- Regioselective cross-coupling reactions under modfied Suzuki and Still cross-coupling reactions with copper catalysis.
- Metal-free biaryl coupling reaction in the presence of dimethyl carbonate as a solvent.
- Suzuki-type cross-coupling reaction with pentavalent triarylantimony diacetates in the absence of a base.
It can also be used to prepare:
- Himbacine analogs as thrombin receptor antagonists and potential antiplatelet agents.
- Trisulfonated calixarene upper-rim sulfonamido and their complexation with trimethyllysine epigenetic mark.
- Antimalarial compounds via Suzuki cross-coupling.
- Deoxyuridine derivatives.

2-[5-(4-Amidinophenyl)-furan-2-yl]-5,6,7,8-tetrahydro-imidazo[1,2-a]pyridine-6-carboxamidine acetate salt (7) was synthesized from 2-[5-(4-cyanophenyl)-furan-2-yl]-imidazo[1,2-a]pyridine-6-carbonitrile (4a), through the bis-O-acetoxyamidoxime followed by hydrogenation in glacial acetic acid. Compound 4a was obtained in four steps starting with two successive brominations of 2-acetylfuran first with N-bromosuccinimide, and second with bromine
