An added bonus in the optimization of a catalyst for the hydrostannation with tin hydrides was the discovery that molybdenum isonitrile complexes are also suitable for distannations. Further developments in this respect led to a new tungsten isonitrile complex, which catalyzed this reaction highly efficiently and selectively (see scheme, THP=tetrahydropyranyl).
