Mode opératoire

Vinyltrichlorosilane (16.8 g, 104 mmol) was heated to 60° C. and 100 μL 10% H2PtCl6/IPA-solution was added. 1,1,1,4,4-pentachloro-1,4-disilabutane (20.4 g, 77.7 mmol) was added slowly during 20 min so that the temperature did not exceed 100° C. The reaction was allowed to proceed for 12 hours at 100° C., after which it was distilled under vacuum at 115-130° C./<1 mbar. The yield was 31.5 g (74.3 mmol, 96%).
