标题:白光引发 Mn2(Co)10/hfip 催化烯烃的反马尔可夫尼科夫氢化硅烷化
摘要: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.

摘要:The invention relates to novel compounds of formula (III) that can be used as heterocyclic dyes of unique structure and properties. These compounds can be obtained in a three-step synthesis from simple substrates. The compounds according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the compounds according to the invention are used in organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
