Pd-Catalyzed Arylation/Oxidation of Benzylic C–H Bond
摘要:
A palladium-catalyzed benzylic C-H arylation/oxidation reaction leading to diaryl ketones has been accomplished. The indispensable role of the bidentate system is disclosed for this sequential process. This chemistry offers a direct new access to a range of diarylketones.

A copper‐catalyzed, cross‐dehydrogenativecoupling of anilines with sodium and lithium sulfinates was developed. By using a cooperative reaction system with Mn(OAc)3 as stoichiometric co‐oxidant a highly selective para‐functionalization of anilines was accomplished. Various functional groups were tolerated and the desired products were obtained in high yields. This method not only provides a novel
A simple and practical approach for a direct remote C-H etherification of arylamines with alcohol is developed herein by using a solid-supported Pt catalyst, hence providing a valuable method for the synthesis of aromatic ethers. The catalyst can easily be recovered from the reaction mixture and reused for six times without apparent loss of activity. Control experiments suggest that a radical pathway
