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.

An oxidative cross-coupling between directing substrates and benzyl bromides via the combined effect of oxidants TBHP and NMO, catalysed by Pd(ii) has been investigated. Benzyl bromides served as efficient aroyl surrogates in this substrate directed C-H f

A facile and efficient way for the synthesis of the acylated 2-arylbenzoxazoles and 2-arylbenzothiazoles by heterocycle-directed ortho-acylation was developed. This reaction was performed in chlorobenzene, using arylmethyl alcohols and tert-butyl hydroperoxide (TBHP) as the easily accessible acyl source and the oxidant, respectively, affording the desired products in moderate to good yields.
