反应条件: temp:16.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Into a 250 ml flask equipped with a magnetic stirring bar, addition funnel and calcium sulfate drying tube is placed a solution of 10.84g (0.06 mole, 98.66% pure) of 2,5-dimethyl-2,5-dihydroperoxyhexane in 120 ml of anhydrous ether. The solution is cooled to 16° C. and a solution of 8.77g (0.06 mole) of bis(dimethylamino) dimethylsilane in 30 ml of anhydrous ether is added slowly dropwise. The reaction temperature is maintained between 15° and 20° by use of an ice bath and by adjusting the rate of addition. After the addition is complete, the solution is stirred at room temperature for one hour. The solution is filtered to remove a small amount of suspended solid. The solvent is removed by distillation yielding 13.75g of 3,3,6,6,9,9-hexamethyl-1,2,4,5-tetraoxa-3-silacyclononane (theoretical yield 14.05g, 97.9%; A.O. analysis 13.32%, theoretical 13.67%, 97.4% pure). The infrared spectrum of the reaction product of this example is identical to the spectrum of material produced in Example 1.

实验步骤: A 2 L 3 neck flask equipped with a magnetic stirrer, Frederich's condensor and an addition funnel was charged with 361 mls of bis(dimethylamino)dimethylsilane and an equal volume of tetrahydrofuran. At ambient temperature, 116 mls of anhydrous ethanol was added over one hour. Dimethylamine evolved. The mixture was transferred to a single neck flask and distilled. 264 g of dimethyl(dimethylamino)ethoxysilane, (b.p. 115°-118° C.), was recovered. The mixture was transferred to a single neck flask distilled 264 g of dimethyl(dimethylamino)ethoxysilane, (b.p. 115°-118° C.), was recovered
