In this dissertation, the synthesis of new allenylidene complexes and their reactivity towards nucleophilic and dipolar substrates is described. The synthesis of new π-donor-substituted allenylidene complexes was achieved. These, as well as complexes already known from the literature, were investigated with respect to their reactivity towards simple nucleophiles, dinucleophiles and dipolar reagents. The dipolar diazomethanes reacted with the π-donor-substituted allenylidene complexes to give butatrienemetal complexes. However, the newly formed ligand is not bound to the metal via one of the π double bonds, but rather in an unusual η1 coordination mode.
