反应详情

In a 1000 mL round bottom flask equipped with a Teflon-coated stir bar and placed in a water bath at room temperature are added tetramethyldisiloxane (134 grams, 1 mole) and allyl methacrylate (126 grams, 1 mole). The reaction is induced by the addition of Karstedt's catalyst (0.5 mL) and the charge is stirred for 3 hours. At this point triphenylphoshine (10 mL) is added and the charge is vacuum distilled (0.1 milibar) at 50° C. The product, 112 grams of a colorless liquid, is rectified on a spinning band column (75 plates, 0.3 mbar) to yield 41 g (16%) of SiH-MA, with a boiling point of 62° C.
