Phenylboronic acid, coupling with heterocyclics

By utilizing a solid support-based tetradentate A-heterocyclic carbene-palladium catalyst, cross couplings of aryl bromides with phenylboronic acid were achieved in neat water under air.121 A high ratio of substrate to catalyst was also realized. [Pg.190]

N-Heterocyclic carbene ligands were used with good results in the sluggish coupling of electron-rich aryl chlorides with phenylboronic acid. These ligands enabled... [Pg.687]

The BTEE-PMO (BTEE, l,2-bis(triethoxysilyl)ethane) functionalized with a bulky N-heterocyclic carbene was prepared by Hao et al. They were used as catalysts for the Suzuki coupling reaction. These materials also exhibited enhanced activity and selectivity [81]. The PdL (silylated carbapalladacycle precursor)-PMO was applied to the Suzuki reaction of p-bromobenzoic acid and phenylboronic add [65]. The results showed high catalyst activity with short reaction times compared to PdL-Si02 (synthesized by co-condensation of precursors and SiOj) due to the benefidal influence by increased porosity and regular distribution of the active site. [Pg.104]
