【摘要】 报道在丙烯酸酯类氢硅化中,基团效应对氢硅化反应活性的影响和对氢硅化反应产物中异构体比率的影响。α-Me使氢硅化反应活性大大降低,且产物中β-加成物比率增多,当相同的丙烯酸酯类骨架时,OR基增大,氢硅化反应活性也增大,产物中β-加成物比率也有增加趋势,由此,提出氢硅化机理中的关键中间体。更多还原

【Abstract】 In this paper, influence on reaction, activity, and ratio between isomers in hydrosilylation of acrylic acid ester series had been systematically investigated by α-Me and OR group. When there is an α-Me on the skeleton structure of acrylic acid ester, the reaction activity of hydrosilylation deereases greatly, but the ratio of β-adduct rises obviously. However, when there is the same group on the skeleton structure, the reaction activity of hydrosilyla tion and the ratio of β-adduct increase with the OR group., The structure of the key medium in the mechanism of hydro ilylation. was also suggested.更多还原
