核磁共振法研究聚甲基-氢-硅氧烷的硅氢化反应

核磁共振法研究聚甲基-氢-硅氧烷的硅氢化反应 STUDY ON THE HYDROSILYLATION REACTION OF UNSATURATED COMPOUNDS WITH POLYMETHYL HYDROSILOXANE BY 1 HNMR SPECTROSCOPY 令孟芝 Meng Lingzhi first-author 黄麒麟 Huang Qiling 张先亮 Zhang Xianliang 本文用 1 HNMR跟踪的方法,研究了在四甲基-1,3-二乙烯基二硅氧烷铂络合物存在下,聚甲基-氢-硅氧烷与七种不饱和化合物的硅氢加成反应。反应温度和溶剂对四甲基-1,3-二乙烯基氧烷铂络合物的催化活性和选择性方面的影响也进行了初步探讨。 HNMR traching technique has been used to study the hyarosilylation reaction of olefins with polymethylhydro-siloxane in the presence of tetramethy 1-1, 3-divinyldisiloxane Pt complex as catalyst. Seven olefins （dodecene, ω-chloroundecene, undecenyl acetate, p-chloro-allyl benzene, cyclohexene, allyl acetate and allyl glycidyl ether） were used as substrate. The influences of substrate, temperature and solvernt on the activity and selectivity of tetramethyl-1, 3-divinydisiloxane Pt-complex as catalyst have also been studied. 核磁共振氢谱 硅氢化反应 聚硅氧烷 铂络合物 ’HNMR hydrosilylation polysiloxane platinum complex 1989-01-01 2021-04-01 1
