Versuchsvorschrift

Using the same apparatus and procedure described in EXAMPLE 1, 25.3 g (0.21 mol) of vinyldimethylchlorosilane and 50 μl of 1% chloroplatinic acid in isopropanol were added to the flask. Through the dropping funnel was added dropwise 10 g (0.07 mol) of allyldichlorosilane for 30 rain at 80° C. and the solution was further reacted for 2 hrs to complete the reaction. Vacuum distillation (48°-52° C./0.5 torr) of the product mixture gave 16.2 g (89%) of 7-methyl-4,4,7-trichloro-4,7-disila-1-octene.
