2-Thiopheneboronic acid Usage And Synthesis
Chemical Propertieswhite to light yellow crystal powder
Uses2-Thiopheneboronic acid can be used as reagent used for Palladium-catalyzed Suzuki-Miyaura cross-couplings; Alkylation, boration, coupling reaction, Suzuki coupling, and halogenation of fluorenyl bromide ;Chain-growth catalyst transfer polycondensation of conjugated alternating copolymer; Ferric perchlorate-promoted reaction of fullerene to give fullerenyl boronic esters.
Uses2-Thienylboronic Acid is a reagent used for palladium-catalyzed Suzuki-Miyaura cross-couplings. It is also used in preparation of photophysical properties of oxygen-containing polycyclic aromatic triptycenes.
