arenes bearing ortho‐directing groups (DG) in the presence of a ruthenium catalyst and aryl iodide is presented. The reaction is general for variously substituted aryl iodides to giveketones in moderate to good yields, and water serves as the solvent. The system is highly selective towards the mono‐carbonylativearylation by ortho CH functionalization. cod=cyclo‐1,5‐octadiene.

The decarbonylation of 2-pyridyl-substituted ketones via transition metal-catalyzed carbon–carbonbondactivation provides ready access to a variety of biaryl compounds. The highly efficient and general method provides reliable decarbonylation of benzophenones including a range of functional groups and substitution patterns. The methodology has also proven highly efficient for heteroaromatic substrates
