Simple, efficient procedures for the monoarylation of acetate esters and arylmethyl ketones using arylchlorides are presented. Previously, no general method was available to ensure the highly selective monoarylation of these classes of substrates using arylchlorides. Using palladium precatalysts recently reported by our group, these reactions are easily accomplished under mild conditions that tolerate

A visible‐light‐induced Negishicross‐coupling is enabled by the activation of a Pd0–Zn complex. With this photocatalytic method, the scope of deactivated aryl halides that can be employed in the Negishicoupling was significantly expanded. NMR experiments conducted in the presence and absence of light confirmed that the formation of the palladium–zinccomplex is key for accelerating the oxidative

heteroaryl tert-butyl acetates occur with complete branched selectivity and very high enantioselectivity. The initial adducts undergo acid promoted decarboxylation in situ to provide alkylated heteroarenes possessing defined β-stereocenters. The processes are postulated to proceed via a stereodefined chiral Ir-enolate, which arises upon heteroarenedirected enolization of the heteroaryl acetate precursor. The
