Procedimiento

A flask equipped with a stirrer, reflux condenser, dropping funnel and thermometer was charged with 99.2 g (0.5 mole) of 1-allyl-4-trimethylsilylpiperazine and 0.65 g of a toluene solution of platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (platinum content 3 wt %) and heated at 70° C. Once the internal temperature became constant, 67.1 g (0.5 mole) of methyldiethoxysilane was added dropwise over 4 hours. Stirring was continued for a further one hour at the temperature. The reaction solution was distilled, collecting 130.8 g of a fraction having a boiling point of 105-106° C./30 Pa.
