Abstract
The direct arylation of aliphatic ketones has been developed via Pd-catalyzed β-C(sp3)-H bond functionalization with 2-(aminooxy)-N,N-dimethylacetamide as a novel transient directing group (TDG), which showed remarkable directing ability to generate arylated products in moderate to good yields. Furthermore, the reaction can tolerate abundant substrate of ketones and aryl iodides. This study expands the scope of applications for TDGs.

Abstract
Ru(II)-catalyzed chelation-assisted highly regioselective C8-hydroxylation of 1,2,3,4-tretrahydroquinolines has been developed. Various 1,2,3,4-tetrahydroquinolines underwent smooth C8-H hydroxylation with cheap and safe K2S2O8 as the oxidant and oxygen source to furnish the corresponding products in good to excellent yields with high tolerance of the functional groups. The choice of a readily installable and removable N-pyrimidyl directing group is the key to catalysis. Mechanistic studies suggest the involvement of a six-membered ruthenacycle intermediate in the catalytic cycle. The method can also be extended to the direct hydroxylation of other (hetero)arene C-H bonds.
