Acetylene → HCID 19601757, compound

Participants

Reaction Steps

Hydrosilation of acetylene with bis(dichlorosilyl)trichlorosilylmethane in the presence of Pd(PPh3)4. Into the same apparatus as described in Example 1 were added 1.01 g of bis(dichlorosilyl)trichlorosilylmethane, 0.103 g of Pd(PPh3)4, and 25 ml of dried benzene to form a mixture. Acetylene gas was blown into the mixture at a rate of 90 ml per minute for 3 hours. The resulting mixture was vacuum distilled at 67 Pa to yield a mixture comprising 0.89 g of 1,1,3,3-tetrachloro-2-trichlorosilyl-1,3-disilacyclopent-4-ene (TCD-GC area 50.3%).
