Procedure: To the silane mixture comprising dimethylmethoxychlorosilane as produced by the disproportionation reaction in (a) above, was added 150 ml of toluene to dissolve the silanes in toluene, and to give a toluene solution of said silane mixture. To the toluene solution was added dropwise the THF solution of tert-butyl magnesium chloride as produced in Example 20, through a dropping funnel, at 40° C.-50° C. over 1 hour. Then, the resulting mixture was stirred at 70° C. for 4 hours. The Grignard reagent could react with dimethylmethoxychlorosilane contained in the said toluene solution, to produce tert-butyldimethylmethoxysilane. as produced in Example 20, through a dropping funnel, at 40° C.-50° C. over 1 hour

Procedure: 16.8 ml (0.22 moles) of a suspension of sodium in toluene at 30% are charged into a 250 ml flask. The mixture is diluted with 100 ml of THF and cooled to 0° C. 18.5 ml (0.22 moles) of cyclopentadiene diluted in 50 ml of THF are slowly added dropwise (about 60 minutes). The resulting solution is left under stirring at room temperature for a whole night, is then cooled to 0° C. and 29 ml (0.22 moles) of methoxydimethylchlorosilane fresh distillate (PETRARCH: 90%) are slowly added dropwise. The reaction is carried out at 0° C. for 3 hours. After filtration of the salt formed and evaporation of the solvent, a dark yellow oily liquid is obtained which, on distillation at 160°-162° C. gives 7.5 g of the desired product with a purity of 95.5% (GC), and a yield of 24%. are slowly added dropwise (about 60 minutes) The resulting solution is left is then cooled to 0° C. After filtration of the salt formed evaporation of the solvent a dark yellow oily liquid is obtained which on distillation at 160°-162° C.
