Abstract A well‐ordered strategy of sulfoxonium ylides as a directing group well carbene source for the Ru‐catalysed [4+2] and Rh‐catalysed [4+1] carbo‐annulations with maleimides has been described. These novel methodologies have successfully established synthesis complex spiroindanones benzoisoindoles containing compounds by transition metal‐mediated C−H activation/functionalization reactions. Further, annulated were obtained in absence any oxidant. possible rationale remarkable divergent selectivity between two catalysts proposed.
