isoquinolines from aryl ketone O-acyloxime derivatives and internal alkynes has been developed using [Cp*RhCl2]2−NaOAc as the potential catalyst system. The present transformation is carried out by a redox-neutral sequence of C−H vinylation via ortho-rhodation and C−N bond formation of the putative vinyl rhodium intermediate on the oxime nitrogen, where the N−O bond of oxime derivatives could work as an internal
