ABSTRACT 2‐Aryl‐ 4H ‐benzo[ d ][ 1 , 3 ]oxazin‐ 4 ‐one derivatives can be directly alkenylated with alkyl acrylates using a facile Ru (II)‐catalyzed process; Cu (OAc) 2 •H O as an oxidizer through formation of pentagon cyclic complex imine‐Ru (II) for C–H activation is described. The unique catalytic reaction well matched miscellaneous olefins such vinyl ketones, acrylonitrile, and acrylates. aryl rings bearing electronically diverse substituents tolerated the conditions to provide ortho‐alkenylation products in high regioselectivities admissible yields.
