The Pd/CeO2 system behaves as an efficient precatalyst for the Suzuki-Miyaura cross-coupling under mild conditions (298 K, in air) in ethanol/water A broad range of aryl bromides. Including those deactivated, and arylboronic acids under went Suzuki-Miyaura coupling with quantitative GC yields of asymmetric biaryls. Isolated yields and purity of the Coupling products were good to excellent. A careful investigation through a series of suitable tests unequivocally showed that the C-C cross-coupling is accomplished via homogeneous mechanism by leached palladium(0). Noticeably.
