论文部分内容阅读
现行的基础有机化学教材均介绍过诸如乙烷、丁烷、环己烷和十氢萘的构象。并不同程度地涉及到它们的稳定性和化学行为的关系。从讨论中已得出这样的结论:在脂肪族化合物中,最稳定的构象一般都是完全交叉式,且两个最大的基团相距最远,进而使分子中各非键原子之间的相互排斥作用达到最小的程度。我们还知道,环己烷和其它同型物中,椅式构象比船式构象稳定。由此,我们又得出这样的结论:一个化合物中含有最多的对位交叉组合的那种构象是占优势的构象,即是最稳定的构象。下面,本人就构象的稳定性和反应的活性之间的关系谈几点看法。
The current basic organic chemistry textures have introduced conformations such as ethane, butane, cyclohexane and decalin. And to varying degrees related to their stability and the relationship between chemical behavior. From the discussion it has been concluded that in aliphatic compounds the most stable conformations are generally perfectly crossed and the two largest groups are the furthest apart which in turn leads to mutual Exclusion to a minimum extent. We also know that in cyclohexane and other isoforms, the chair conformation is more stable than the boat conformation. From this, we come to the conclusion that the conformation containing the largest number of para-locus combinations in a compound is the predominant conformation, the most stable conformation. Below, I talk about the relationship between the stability of the conformation and the activity of the reaction.
