الإجراء التجريبي

306 g (2.00 mol) of divinyldichlorosilane, 539 g (4.80 mol) of potassium tert-butoxide and 3.0 L of dry hexane were charged in a 5 L four-necked flask equipped with a dropping funnel and a mechanical stirrer in a stream of nitrogen, and reaction was carried out for 17 hours under reflux with hexane. After completion of the reaction, potassium chloride residue as a by-product was removed by filtration, and the obtained filtrate was distilled under reduced pressure to obtain 257 g (1.13 mol) of divinyl di-tert-butoxysilane as an aimed product. The yield was 56.5%.
