Abstract
The reaction of 1,1,3,3-tetramethyl-1,3-disilanona-4,8-diyne (7) and 1 ,1,4,4-tetramethyl-1,4-disiladeca-5,9-diyne (8) with R-CpCo(CO)(2) (R= H, CH3) allowed to stop the reaction at the stage of tricyclic interme diates, the latter could be reacted again with R-CpCoL2(L-2=COD,(CO)(2 )) to yield CpCo-capped cyclobutadiene-superphanes with different subs tituents in the two Cp ligands.
