过渡金属参与的联苯烯衍生物碳-碳键活化反应的研究进展

Recent Advances of C—C Bond Activation of Biphenylenes with Transition-metals

碳-碳键的活化反应具有原子经济性和步骤简便性,可以从简单易得的原料合成复杂的有机分子。由于联苯烯化合物中含有较大环张力的四元环结构,联苯烯类衍生物能够与低价金属发生氧化加成反应,从而生成金属杂五元环中间体,生成的金属杂五元环中间体可与多种底物进一步发生反应,生成环状有机化合物;此外还可以高效催化其他反应。综述了由过渡金属(Ni、Ir、Rh、Pd、Au、Pt)与联苯烯类衍生物氧化加成反应而引发的碳-碳键活化反应的研究进展。

The C-C bond activation process presents a highly atom,and step economical access to complex organic molecules from readily available simple starting materials.Due to the high strain energy arising from the four membered ring moiety,the oxidative additions of biphenylenes to the low-valent metals tend to occur generating five membered metallocycles which can go on to give various products or serve as catalysts for other reactions. The review focuses on C-C bond activation of biphenylenes triggered by their oxidative additions to the low-valent metals( Ni,Ir,Rh,Pd,Au,Pt) and their application in organic synthesis.
