The use of a dual palladium/organic photoredox catalytic system enables the directed arylation of arenes with aryldiazonium salts with a broad substrate scope at room temperature under mild reaction conditions. This study thus serves as not only an alternative route for the biaryl motifs but also a new example for the application of an organic photoredox catalyst.

Bring it on! An effective Pd‐catalyzed orthoolefination of various acetanilides has been developed. This transformation has a broadsubstratescope and wide functional‐group tolerability, regardless of the electronic and steric properties of acetanilidesubstrates, providing a straightforward access to highly functionalized arenes.
This invention provides a compound of formulae (I) or (II) having the structure or a pharmaceutically acceptable salt thereof which are useful for the treatment of the inflammatory component of diseases and are particularly useful in treating atherosclerosis, myocardial infarction, congestive heart failure, inflammatory bowel disease, arthritis, type II diabetes, and autoimmune diseases such as multiple sclerosis and rheumatiod arthritis.

A new atom-economical process of direct oxidative intermolecular functionalization of aniline derivatives by simple arenes was developed. The products were formed in a highly regioselective manner under metal-free conditions at ambient temperature.
aromatic ring with high site selectivity remains a challenging area in organofluorine chemistry. We herein report a highly para-selective C–H perfluoroalkylation of aniline substrates using the molybdenumhexacarbonyl catalyst. Various substituted anilids derived from anilids were well-tolerated, affording the corresponding products in moderate to good yields. Preliminary mechanism studies and density functional
