The CsF-18-crown-6 mediated reactions of disubstituted acetylenes Me3SiCCMMe3 (M=C, Si, Ge, Sn) with phenylacetylene and 2-methyl-5-pyridylacetylene in benzene have been studied. The first step of the reaction is the deprotonation of

The synthesis of mono-, di-, tri- and tetraalkynylated tricartaonyl(cyclobutadiene)iron complexes is accomplished by a repetitive metalation/iodination/coupling sequence. Application of this sequence leads to the synthesis of oligomeric cyclobutadiene complexes with various topologies, inter alia to the synthesis of a perethynylated aimer 24. Alternatively a one-step coupling procedure (Stille-Farina) has been used to synthesize tetraalkynylated tricarbonyl(cyclobutadiene)irons 26, VCH Verlagsgesellschaft mbH, : 1996.
