Catalytic: Ruthenium(II)biscarboxylate complexes enabled highly effective hydroarylations of unactivatedalkenesthrough CH bond activation. This method has a broad substrate scope and allowed for versatile functionalizations of highly fluorinated alkenes.
Cut to the chase: A ruthenium complex derived from 1‐adamantyl carboxylate (1‐AdCO2−) enabled highly regioselective intermolecular directalkylation of arenes with unactivated primary and secondary alkyl halides bearing β‐hydrogen atoms (see scheme; NMP=N‐methylpyrrolidinone).

catalytic CH bond arylations on heteroaryl‐substituted arenes with widely available aryl chlorides, which set the stage for the preparation of sterically hindered tri‐ortho‐substituted biaryls. Likewise, challenging direct alkylations with β‐hydrogen‐containing primary and even secondary alkyl chlorides proceeded on pyridyl‐ and pyrimidyl‐substituted arenes and heteroarenes. The cobalt‐catalyzed CH bond

A process for forming a carbon-carbon bond to couple an aryl or heteroaryl group of a first compound with an alkyl or cycloalkyl moietyof a second compound, the process comprising reacting the first compound with the second compound in the presence of a catalytically effective amount of a neutral or cationic ruthenium(II) catalyst of formula (I).
