This communication describes a new and highly practical Pd(II)-catalyzed method for the regio- and chemoselective oxidative functionalization of arenes and alkanes. Carbon-hydrogen bonds of substrates that contain a variety of directing groups (e.g., pyridine, azobenzene, pyrazole, and imine derivatives) are selectively transformed into esters, ethers, and aryl-halides under mild conditions. The scope

Chelation directed C—H activation reactions that are catalyzed by Pd(11) on Multi-Walled Carbon Nanotubes (MWCNT), Single-Walled Carbon Nanotubes (SWCNT), or graphene are provided. The reactions are used to directly and regioselectively or regiospecifically functionalize specific C—H bonds, e.g. to build complexity into small molecules. Features and advantages of the present invention will be set forth in the description of invention that follows, and in part will be apparent from the description or may be learned by practice of the invention. The invention will be realized and attained by the compositions and methods particularly pointed out in the written description and claims hereof.
