Palladium catalyzed direct arylation of azine N-oxides using aryltriflates to afford the corresponding 2-aryl azine N-oxides is described. The reaction is carried out with a range of both N-oxides and aryltriflates. The arylation can be carried out in sequence to yield differentially diarylated products. The regioselectivity and scope of 3-substituted azine N-oxides are investigated. The method is

Herein, a protocol for the construction of axially chiral biaryls Pd-catalyzed direct C–Holefination of 1-arylisoquinoline -oxides through kinetic resolution have been uncovered. The atroposelective C–Holefination of 1arylisoquinoline -oxides is achieved with alkenes such as acrylates, styrenes, phenylvinyl sulfone, acrylonitrile, and maleimides. The commercially available, cost-effective, and bench-stable
