本文叙述了用动态~1HFT-NMR波谱术研究双(三苯基膦)二氧络铂均相催化硅氢化加成反应,连续进行18小时反应,解析了~1H质子谱峰,并讨论了苯乙烯的β和α位硅氢化加成产物,以β位加成产物为主。还提出了可能的反应机理。
In this paper, the dynamic 1HFN-NMR spectroscopy was used to study the homogeneous hydrosilylation reaction of bis (triphenylphosphine) dioxygen platinum and the reaction was continued for 18 hours. The proton peaks of 1H proton Ethylene β and α hydrosilanes addition products, β-adduct-based products. A possible reaction mechanism is also proposed.
