Silver catalyzed pyridine-directed acceptorless dehydrogenation of secondary alcohols

A silver catalyzed pyridine-directed acceptorless dehydrogenation of secondary benzyl alcohols was developed. This general procedure delivers ketones with high atom-economy and hydrogen was the sole byproduct. This dehydrogenation reaction has a good functional group tolerance and high efficiency (up to 90% yield and 10,000/1 substrates-to-catalyst ratio).

Pyridine-directed carbon–carbon single bond activation: Rhodium-catalyzed decarbonylation of aryl and heteroaromatic ketones

The decarbonylation of 2-pyridyl-substituted ketones via transition metal-catalyzed carbon–carbon bond activation provides ready access to a variety of biaryl compounds. The highly efficient and general method provides reliable decarbonylation of benzophenones including a range of functional groups and substitution patterns. The methodology has also proven highly efficient for heteroaromatic substrates, including those containing thiophenyl, indolyl, quinolinyl, and pyridine substitution.

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.

Ag1Pd1-rGO nanocomposite as recyclable catalyst for CDC reactions of 2-arylpyridines with aldehydes

Ag1Pd1 nanoparticle-reduced graphene oxide (Ag1Pd1-rGO) nanocomposite was used as an efficient catalyst for the synthesis of aromatic ketones via cross dehydrogenative coupling (CDC) reactions of 2-arylpyridines

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.

Polystyrene-supported Pd(II) complex-catalysed carboacylation of 2-arylpyridines with alcohols via C─H bond activation under solvent-free conditions

Polystyrene-supported N,N-dimethylethylenediamine Pd(II) complex C was used as an efficient catalyst for the synthesis of aromatic ketones via ortho-acylation of sp2 C─H bonds of 2-arylpyridines with alcohols as effective coupling partners. The alcohols were oxidized with tert-butyl hydroperoxide to their corresponding aldehydes in situ and efficiently coupled with 2-arylpyridines to form aryl ketones under solvent-free conditions. Furthermore, catalyst C could be easily recovered by simple filtration and reused for five cycles without any significant decrease in its activity.

Recyclable Pd(II)complex catalyzed oxidative sp2C[sbnd]H bond acylation of 2-aryl pyridines with toluene derivatives

A recyclable polymer–anchored Pd(II) complex C was synthesized and characterized using different spectroscopic techniques. In addition the catalytic efficiency of the Pd (II) complex C was evaluated for ortho-acylation of 2-aryl pyridines with toluene derivatives to form aryl ketones via cross dehydrogenative coupling. In this catalytic process toluene acts as an effective coupling partner upon sp3C[sbnd]H bond oxidation for sp2C[sbnd]H bond acylation of 2-aryl pyridines in the presence of Pd(II)/TBHP system on water. Furthermore, the catalyst C was highly stable and could be easily recovered and reused for four cycles with no significant decrease in its activity and selectivity.
