Procedure

137.8 g trichloro(2,4,4,6,6-pentamethylheptyl)silane, prepared according to example 7, were dissolved in toluene and heated to 100° C. under argon. By means of a dropping funnel were added 220 ml isopropylmagnesium chloride as a 2 molar solution in THF were added to this solution within 1 h. Subsequently the THF was distilled off by means of a column and the reaction mixture was stirred at 100° C. for 20 h. Filtration was carried out for separating the precipitated solid and the product was isolated by vacuum distillation.
