Procedure

Vinyltrichlorosilane (68.8 g, 426 mmol) and cobalt octacarbonyl (700 mg) were placed in a 100 mL rb flask and cooled in an ice bath to 0° C. Dichlorosilane (bp. 8° C., 44.3 g, 439 mmol) was then condensed into the flask, The system was allowed to warm up to room temperature during night. Distillation at 60 . . . 62° C./8 mbar gave 1,1,1,4,4-Pentachloro-1,4-disilabutane (120.8 g, 460 mmol) in 93% yield.
