亲核消除,分为E1 and E2 and E1cb 两种很复杂,还是自己看书吧,没2天是不可能懂一点的（挺深的）《基础有机化学》这本书的机理很不错,但不推荐（太难）附：消除反应消除反应（elimination reaction）,使反应物分子失去两个基团（见基）或原子,从而提高其不饱和度的反应. 分类 按失去的两个基团在...
至于E1cb的分类,这涉及到了无聊的物理有机,而且意义不大。有兴趣的可以康康维基百科:https://en.wikipedia.org/wiki/E1cB-elimination_reaction,顺便还可以了解一下Kinetic Isotopic Effect。 好啦!至此,亲核取代以及消除反应就讲完了。接下来,我们会开始烯烃的反应,然后是醇和炔。从第一篇到此的内容都是合成的基础。

The chlorine leaving group isotope effect has been measured for the base-promoted elimination reaction of 1-(2-chloro-2-propyl)indene (1-Cl) in methanol at 30 °C: k35/k37 = 1.0086 ± 0.0007 with methoxide as the base and k35/k37 = 1.0101 ± 0.0001 with triethylamine (TEA) as th...

An addition-pseudorotation-elimination pathway is proposed for the first stereospecific ring-expansion reaction of chiral diazaphospholidine oxides by a 1... O Legrand,JM Brunel,G Buono - 《Angewandte Chemie International Edition》 被引量: 220发表: 1999年 Hydroisomerization of n-hexane over plati...
Byintroducing a carbon functionality at 2-position of chromane,the formal asymmetric functionalization of the 3-position of 2-substitutedchromane has been realized via a highly chemo-, regio-, and stereoselectiveorganocatalytic cascade reaction in a sequential one-pot manner involvingan E1cB mechanism ...
Elimination reactionsMechanistic borderlineE2 and E1cb mechanismsElimination reactions of XC_6H_4CH_2CO_2C_6H_3-2-Y-4-NO_2 have been studied under various conditions.When X was moderately electron-withdrawing,Y=H,and base-solvent was R_2NH-MeCN,the reaction proceeded by the E2 mechanism via...
Artificial Neural Networks vs Linear Regression in a Fluid Mechanics and Chemical Modelling Problem: Elimination of Hydrogen Sulphide in a Lab-Scale Biofilter A biofilter is a biological reactor in which a certain pollutant is eliminated by the action of microorganisms. In this work, the removal eff...
