Nickel-catalyzed regioselective C-H acylation of chelating arenes: A new catalytic system for C-C bond formation: Via a radical process and its mechanistic explorations

An unprecedented acylation at the ortho C-H bond of chelating arenes via the Ni(ii)-catalyzed cross dehydrogenative coupling strategy has been developed here. This new procedure exhibits excellent regioselectivity and good functional group tolerance. This discovery could be of great importance for the C-H acylation reactions of chelating arenes without any extraneous directing group and for the application of nickel-catalyzed C-H activation. Mechanistic investigations into the reaction process are also described.

Monodisperse CuPd alloy nanoparticles as efficient and reusable catalyst for the C (sp2)–H bond activation

Metal-catalyzed selective activation of C–H bonds is very important for the construction of a variety of biologically active molecules. Supported alloy nanoparticles are of great interest in various catalytic applications due to the synergistic effects between different metals. Here, well-dispersed CuPd alloy nanoparticles supported on reduced graphene oxide (rGO) were synthesized and found to be highly efficient and recyclable catalyst for the chelation-assisted C (sp2)–H bond activation. Aromatic ketones or esters were synthesized via the cross-dehydrogenative coupling (CDC) reaction between 2-arylpyridines and alcohols or acids. Moreover, the catalyst was recovered and used for five times without significantly losing activity.

Polystyrene supported Dichloro-(8-aminoquinoline)-Palladium(II) complex catalyzed C[sbnd]H bond activation for ortho-acylation of 2-aryl pyridines

Polystyrene-supported Dichloro-(8-aminoquinoline)-Pd(II) complex C was synthesized and its catalytic efficiency was evaluated for ortho-acylation of 2-aryl pyridines with alcohols to form aryl ketones via cross dehydrogenative coupling. In addition in the presence of Pd(II) complex, toluene derivatives were also employed as an effective coupling partner for synthesis of aromatic ketones. Furthermore, this catalyst was highly stable and could be easily recovered by simple filtration and reused for four cycles with no significant decrease in its activity and selectivity.
