氟化钾催化取代酚与硅氢化合物的反应

The Reaction of Substituted Phenols with Hydrosilanes catalyzed by Potassium Fluoride

硅氢化合物与酚的反应是合成芳氧基硅烷的方法之一,它与氯硅烷与酚的反应相比,具有副反应少、产率高、反应时间短等优点。该反应可被多种催化剂所催化。

The reactions of various substituted phenols X OH (X=H, p-CH_3, p-CH_3O,p-NO_2, p-Cl, p-Bu~?, p-Br, o-CH_3, o-Cl, o-NH_2 and 2,6-(CH_3)_2 resp.) with HSiMeEtPh andof phenols with various hydrosilanes HSi(R)MePh (R=H, CH_3, C_2H_6, i-C_4H_9 and C_6H_5) inthe presence of potassium fluoride gave twenty one new aryloxy organosilicon compoundswhich have been identified by elemental analyses, IR,~1HNMR and the relationship betweenthe structure and reactivity is discussed.
