Procedure
Using the same apparatus and procedure described in EXAMPLE 1, 7.7 g (0.1 mol) of allylchloride and 60 μl of 1% chloroplatinic acid catalyst were added to the flask. Through the dropping funnel was added dropwise 6.6 g (0.05 mmol) of allyldimethoxysilane for 30 min. while refluxing. After confirming by gas chromatography to complete the reaction, the product was fractionally distilled under vacuum (59°-62° C./0.5 torr) to give 8.0 g (81%) of 7-chloro-4,4-dimethoxy-4-sila-1-heptene.
