The nickel-catalyzed reation of 1,1'-bis(dimethysilyl)ferrocene[1] with carbonyls such as benzaldehyde, 4-cyaonbezaldehyde, trimethylacetaldehyde, acethon, and benzophenone afforded 3-oxa-2,5-disilacyclo-1,1'-ferrocene. In contrast, the reation of [1] with isobutyraldehyde under the same reation condition yielded the diinsertion products formed via the insertion of two aldehyde ligands into the Si-H bond of 1,1'-bis(dimethy)ferrocene.

The reaction of 1,1'-bis(dimethylsilyl)ferrocene with various aldehydes in the presence of a catalytic amount of Ni(PEt3)4 lead to the acyclic products by monohydrosilylation. The same reaction in the presence of a catalytic amount of (C2H4)Pt(PPh3)2 leads to the different cyclic six membered ring compound by double silylation. Platinum catalyzed double silylation of 4-cyanobenzaldehyde was generated 5,6-ferrocenylene-1,1,4,4,-tetramethyl-2-oxa-2- cyanophenyl-1,4-disylacyclehexane which was crystallized to have crystal structure.
