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.
