selectivity by the precise monitoring of the experiments with in situ FTIR and NMR spectroscopies. More than twenty silsesquioxanes bearing reactive groups (OH, Br, NR2, CO, COOR, NCO, epoxy, SiR3) commonly used in organic and polymer chemistry, were obtained, isolated and characterized by 1H, 13C, 29Si NMR and MALDI TOF. Importantly, in the presented syntheses, commercially available reagents and catalysts
这项工作中提出的研究全面描述了在不同类型的催化剂存在下,含有(HSiMe 2 O)(i Bu)7 Si 8 O 12的多种烯烃的氢化硅烷化反应。通过用原位FTIR和NMR光谱法精确监控实验,对烯烃,催化剂和反应条件对工艺效率和选择性的影响给予了特别关注。获得,分离和表征了20多个有机和聚合物化学中常用的带有反应性基团(OH,Br,NR 2,CO,COOR,NCO,环氧基,SiR 3)的倍半硅氧烷。13 C,29 Si NMR和MALDI TOF。重要的是,在所提出的合成中,使用了可商购的试剂和催化剂,这意味着所提出的方法可以容易地重复,迅速扩大规模并广泛应用。
