A dissymmetric piano-stool ruthenium(II) complex bearing different halogens on the rotor part was efficiently prepared and subsequently used as key building block in the modular synthesis of rotative molecular machines via palladium-catalysed "Sonogashira/Suzuki-Miyaura" sequences. Applying this novel synthetic route to various cross-coupling partners, prototypes of molecular winches and gears specifically designed for studies at the single-molecule scale were efficiently obtained.
