A novel 4-aminoantipyrine-Pd(II) complex catalyzes Suzuki–Miyaura cross-coupling reactions of aryl halides
A simple and efficient catalytic system based on a Pd complex of 4-aminoantipyrine, 4-AAP-Pd(II), was found to be highly active for Suzuki-Miyaura cross-coupling of aryl iodides and bromides with phenylboronic acids under mild reaction conditions. Good to excellent product yields from the cross-coupling reaction can be achieved when the reaction is carried out in ethanol, in the open air, using...
متن کاملApplication of dimeric and monomeric ortho-palladated complexes as an efficient catalysts for Heck cross-coupling reaction
The catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2)2) and [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)](3), was investigated in Heck cross-coupling reaction. These complexes are more active and efficient catalysts for Heck cross-coupling reaction. The palladium complexes 2 and 3 is employed in the Heck cross-coupling reaction between styrene a...
متن کاملAu−Pd Nanoparticles Dispersed on Composite Titania/Graphene Oxide-Supports as a Highly Active Oxidation Catalyst
The control over both the dispersion and the particle size distribution of supported precious metal nanoparticles used in heterogeneous catalysts is of paramount importance. Here, we demonstrate the successful formation of highly accessible and well dispersed gold−palladium nanoparticles, stabilized with two-dimensional graphene oxide, that itself is dispersed by intercalated titania particles ...
متن کاملPd-Catalyzed Aerobic Oxidative Coupling of Arenes: Evidence for Transmetalation between Two Pd(II)-Aryl Intermediates
Pd-catalyzed aerobic oxidative coupling of arenes provides efficient access to biaryl compounds. The biaryl product forms via C-H activation of two arenes to afford a Pd(II)ArAr' intermediate, which then undergoes C-C reductive elimination. The key Pd(II)ArAr' intermediate could form via a "monometallic" pathway involving sequential C-H activation at a single Pd(II) center, or via a "bimetallic...
متن کاملHighly efficient photocatalytic dehalogenation of organic halides on TiO2 loaded with bimetallic Pd-Pt alloy nanoparticles.
UV irradiation of TiO(2) loaded with bimetallic Pd-Pt alloy particles promotes highly efficient dehalogenation of organic halides with alcohol as a hydrogen source.
