Ru-Catalysis enables to overcome limitations of Pd-catalyzed C-H-alkenylations using sulfonamides. A dual use concept is presented for the catalyst directing group, the acetamide substituent, which can be removed traceless by deacetylation-diazotation-coupling sequence, or by incorporation into the pyrrolo[2,3-c]quinoline skeleton.
