充分取代的环己-1,4-二烯与一个双烯丙基碳原子相连,作为小分子的替代物。安全和方便处理的危险化学品替代品一直很受欢迎。在B(C6F5)3催化的EL-H向π-和σ-供体(CC/CC和CO/CN)的转移反应中,新近引入的具有足够取代度的环己-1,4-二烯起到了EL+/H-等价物的作用。设计了Si-H/Ge-H、H-H甚至C-H键的替代物,并分别成功地应用于离子转移氢硅化/氢胚化、氢化和氢叔丁基化。这些过程及其基本原则在这篇小评中作了总结。讨论了这些转移反应之间的异同以及与这些转化相关的挑战。
Adequately substituted cyclohexa-1,4-dienes with an electrofuge attached to one of the bisallylic carbon atoms serve as surrogates for small molecules. Safe- and convenient-to-handle surrogates of hazardous chemicals are always in demand. Recently introduced cyclohexa-1,4-dienes with adequate substitution fulfil this role as El+/H– equivalents in B(C6F5)3-catalysed transfer reactions of El–H to π- and σ-donors (CC/CC and CO/CN). Surrogates of Si–H/Ge–H, H–H and even C–H bonds have been designed and successfully applied to ionic transfer hydrosilylation/hydrogermylation, hydrogenation and hydro-tert-butylation, respectively. These processes and their basic principles are summarised in this Minireview. The similarities and differences between these transfer reactions as well as the challenges associated with these transformations are discussed.
