With a tricarbonyl(diethynylcyclobutadiene)iron complex as starting material, 7 is prepared in a stepwise fashion by a repetitive deprotonation/iodination/coupling sequence; 7 is a precursor tb the dumbbell-shaped peralkynylated organometallics 8, which are obtained by coupling of 7 with a ditin alkyne or butadiyne.
