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 intermediates, the latter could be reacted again with R-CpCoL2 (L2 = COD, (CO)2) to yield CpCo-capped cyclobutadiene-superphanes with different substituents in the two Cp ligands.
