quantitative and with -Markovnikov selectivity. The method is applicable to terminal alkenes, including those with O-, N- and halogen-containing functional groups, styrene and allylbenzene derivatives, etc., as well as to a wide range of alkyl-, phenyl-, siloxy- and alkoxy-containing tertiary hydrosilanes. These conditions turned out to be most efficient for hydrosilylation of gaseous reagents such as ethylene
这项研究提出了一种高效且温和的烯烃自由基氢化硅烷化方法。该反应在白光下、在 Mn(CO) 预催化剂和 HFIP 作为添加剂的存在下、在室温和空气中进行。在白光下,生成[Mn]•,激活Si–H基团形成Si•并触发自催化过程。 HFIP 作为一种独特的活化剂,能够以接近定量的收率和马尔可夫尼科夫选择性合成产品。该方法适用于末端烯烃,包括带有O-、N-和含卤素官能团的末端烯烃、苯乙烯和烯丙基苯衍生物等,以及广泛的烷基、苯基、甲硅烷氧基和烷氧基。含有叔氢硅烷。事实证明,这些条件对于乙烯和乙炔等气态试剂的氢化硅烷化是最有效的。在这两种情况下,产物在 1 atm 和 rt 下均显示出定量产率。该方法可以在批量和流动模式下轻松扩展。
