molecular wires, alkynemetathesis was investigated as an alternative to palladium-catalyzed coupling reactions for the synthesis of alkynyl ferrocenes. With a Mortreux catalyst system [Mo(CO)6, 4-chloro- or 2-fluorophenol], (1-propynyl)ferrocenes gave the expected homo metathesis products in moderate yields. Because the Mortreux catalyst system is not compatible with 1,1′-dialkynylferrocenes, a nitridomolybdenum
