Abstract
1,1’-Bis(dimethylsilyl)ferrocene과 다양한 aldehydes를 소량의 Ni(PEt3)4 촉매하에서 반응시켰을 경우 hydrosilylation 반응에 의한 비고리형의 monohydrosilylation 된 생성물이 얻어졌다. 그러나 촉매를 Ni(PEt3)4 대신에 (C2H4)Pt(PPh3)를 사용한 경우에는 고리형의 double silylation 된 6각 고리 생성물이 얻어졌다. 특히 Pt 촉매하에서 4-cyanobenzaldehyde silylation 반응은 double silylation 된 5,6-ferrocenylene-1,1,4,4-tetramethyl-2-oxa-2-cyanophenyl-1,4-disilacyclohexane의 결정을 얻었다.

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.
