C-C Bond Formation through Catalytic Functionalization ofBonds, ChXie, Min
当CH键更加acidic,机理比起sear更类似于σ键复分解,值得强调的是,此时可视为CH键断裂成分大于CPd键形成成分(四元环过渡态中),即越缺电子越容易进行反应。 烯烃coupling 两种可能的机理,先活化CHbond或者烯烃,带来区域选择性的区别 有趣的事,关于五六选择性,当以β-H消除脱离循环时,五元环似乎有利,当通过CO插入...

而脂肪族胺的位点选择性芳基化反应,由于能够避免起始原料的前期官能团化(prefunctionalization)步骤,因而,通过惰性键官能团化(如C-H或C-C键官能团化)的方法学,在所有具有潜在应用价值的方法中极具吸引力。在过去十年中,胺的γ-选择性C-H芳基化已经取得较多的研究进展(Figure 1a)。Sanford等[1]通过开发出通过胺C-...
The study and application of transition metal hydrides (TMHs) has been an active area of chemical research since the early 1960s1, for energy storage, through the reduction of protons to generate hydrogen2,3, and for organic synthesis, for the functionalization of unsaturated C–C, C–O and ...

Transition metal-catalyzed direct functionalization of C–H bonds is one of the key emerging strategies that is currently attracting tremendous attention with the aim to provide alternative environmentally friendly and efficient ways for the construction of C–C and C–hetero bonds. In particular, the...
Herein, recent developments for Selectfluor-mediated C–H functionalization of N-heteroarenes are described. This type of C–H bond activation is an attractive and competitive alternative to traditional methodologies, allowing the functionalization of a variety of chemical functions. In addition, Selectfluo...
