摘要
本文通过色谱定量监测,研究了多种取代硅烷RR1R2SiH(R、R1、R2分别为H、Me、Et、Bui、Ph和EtO)与苯酚,在氟化钾存在下,于相同条件下的反应,定量地表征了Si上取代基对其脱氢偶联反应活性的影响。结果表明。
By means of chromatography monitor, the phenolysis of various substituted hydrosilane RR 1R 2SiH(R,R 1,R 2 are H,CH 3,C 2H 5, C 4H i 9, C 6H 5 and C 2H 5O respectively) in the presense of KF at same conditions was studied. The effect of substituents on Si atom in hydrosilanes on their reactivity in phenolysis was quantitatively characterized. The result indicated the electron-withdrawing groups or hydrogen atoms on Si atom were favorable for the reactivity of hydrosilane.
