Abstract
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

니켈 착물을 촉매로 사용한 1,1´-Bis(dimethylsilyl)ferrocene [1]과 carbonyl 화합물 -benzaldehyde, 4-cyanobenzaldehyde, trimethylacetaldehyde, acetophenone과 benzophenone-은 3-oxa-2,5-disilacyclo-1,1′-ferrocene을 생성하였다. 이와 대비되게 동일한 반응조건에서 화합물 [1]과 isobutyraldehyde의 반응에는 1,1′-bis(dimethylsilyl)ferrocene의 Si-H 결합에 2개의 aldehyde ligand가 이중 삽입된 생성물이 형성되었다.
