Phosphine-Catalyzed Si-C Coupling of Bissilylmethanes: Preparation of Cyclic (Cl2SiCH2)2 and Linear Cl 2Si(CH2SiCl3)2 via Silylene and Silene Intermediates

Cyclic and linear carbosilanes, (Cl2SiCH2) 2 (2) and Cl2Si(CH2SiCl3) 2 (3), were produced from phosphine-catalized Si-C coupling reactions of bissilylmethanes, HCl2SiCH2SiX1X 2Cl (X1, X2 = Cl (1), X1 = H, X 2 = Cl (7), and X1 = Me, X2 = Cl (8)). The formation of compounds 2 and 3 suggested competing reaction pathways, involving dichlorosilene [CH2=SiCl2] and dichlorosilylene [:SiCl2] intermediates. Each intermediate was either proposed by the product isolation of the trimerized product (3) or confirmed by trapping experiments with 2,3-dimethylbutadiene and methylene chloride.

PRODUCTION METHOD FOR LINEAR AND CYCLIC TRISILAALKANE

The present invention relates to a preparation method for a linear or cyclic trisilaalkane which is a substance useful in the preparation of polycarbosilane and silicon carbide precursors. Linear or cyclic trisilaalkane and organic trichlorosilane derivatives can be synthesized simultaneously and in high yield by reacting bis(chlorosily)methane having a Si—H bond, either alone or together with an organic chloride, using a quaternary organic phosphonium salt compound as a catalyst. Further, since the catalyst can be recovered after use, the present invention is very economical and is thus effective for mass-producing precursors for organic/inorganic hybrid substances.
