Aryl-Halide versus Aryl−Aryl Reductive Elimination in Pt(IV)−Phosphine Complexes
Journal of the American Chemical Society, 2006Upon the addition of Br2 to complexes (P-P)Pt(Ar)2, two different products were observed, depending on the bite angle of the bidentate phosphine ligand: a Pt(II) aryl bromide complex, the product of C-Br reductive elimination, and Pt(IV) oxidative addition complex.

Aryl–Aryl Bond Formation by the Fluoride‐Free Cross‐Coupling of Aryldisiloxanes with Aryl Bromides
Chemistry – A European Journal, 2011AbstractThe prevalence of the biaryl structural motif in biologically interesting and synthetically important molecules has inspired considerable interest in the development of methods for aryl–aryl bond formation. Herein we describe a novel strategy for this process involving the fluoride‐free, palladium‐catalysed cross‐coupling of readily accessible ...

Strong Metallophilic Interactions in the Palladium Arylation by Gold Aryls
Angewandte Chemie, 2012It's the second step that counts: arylation of Pd by Au takes place through transition states and intermediates featuring strong Au⋅⋅⋅Pd metallophilic interactions. However, the aryl transfer from [AuArL] to [PdArClL(2)] is thermodynamically disfavored and will not occur unless an irreversible Ar-Ar coupling from [PdAr(2)L(2)] follows.

Microwave-Promoted Aminocarbonylation of Aryl Iodides, Aryl Bromides, and Aryl Chlorides in Water
Organometallics, 2006Fast and direct methods have been developed for the small-scale carbonylative preparation of benzamides from aryl iodides, bromides, and chlorides in pure water. The reactions proceed by palladium catalysis using noninert conditions, solid Mo(CO)6 as the CO source, and controlled microwave superheating.

A highly useful, visible-light-driven carboxylation of aryl bromides and chlorides with CO2 was realized using a combination of Pd(OAc)2 as a carboxylation catalyst and Ir(ppy)2(dtbpy)(PF6) as a photoredox catalyst.

Palladium-catalyzed arylation of aryl sulfonamides with cyclohexanones
Journal of Molecular Catalysis A: Chemical, 2014Abstract Pd-catalyzed intermolecular aerobic dehydrogenative aromatizations have been developed for the arylation of aryl sulfonamides with cyclohexanones. Various N -aryl sulfonamides were selectively obtained in good yields using molecular oxygen as oxidant. The reaction tolerated a wide range of functionalities.
