Procedure

Using the same apparatus and procedure described in EXAMPLE 1, 97.9 g (1.46 mol) of allyl cyanide and 350 μl of 1% chloroplatinic acid in isopropanol were added to the flask. Through the dropping funnel was added dropwise 20.6 g (0.15 mmol) of allyldichlorosilane for 30 min at 80° C. and the solution was further reacted for 17.5 hrs to complete the reaction. Vacuum distillation (76-78/0.5 torr) of the product mixture gave 18.76 g (62%) of 4,4-dichloro-7-cyano-4-sila-1-heptene.
