Catalytic amounts of [RuCl 3 (H 2 O) n ] allow for direct arylations via C-H bond functionalization with aryl bromides, bearing a variety of important functional groups.

Generally applicable, palladium-catalyzed direct arylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105-120 8C. Thereby, intraand intermolecular C À H bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups.

Jack of all trades? A ruthenium(IV) carbene complex catalyzes the diastereoselective direct arylation of alkenes using aryl chlorides with high efficiency, which sets the stage for the development of a direct arylation–hydrosilylation sequence (see scheme).
