The first example of an intermolecular carbene–carbene coupling reaction between a Fischer and a Schrock carbene ligand is achieved by coupling of the vinylidene fragment in 1 with the methoxyethylidene ligand in 2 . In the resulting red titanacyclic chromium carbene complex 3 the chromium is coordinated in such a way by the methoxy substituent that the bicyclic framework is virtually planar.
