Abstract
The synthesis of mono-, di-, tri- and tetraalkynylated tricarbonyl(cyc lobutadiene)iron complexes is accomplished by a repetitive metalation/ iodination/coupling sequence. Application of this sequence leads to th e synthesis of oligomeric cyclobutadiene complexes with various topolo gies, inter alia to the synthesis of a perethynylated dimer 24. Altern atively a one-step coupling procedure (Stille-Farina) has been used to synthesize tetraalkynylated tricarbonyl(cyclobutadiene)irons 26.
