在有机化学中,一般把与官能团相连的碳原子叫做α—C,而与α—C原子相连的氢原子叫做α—H。当研究有机化合物性质时,常常遇到α—H原于反应活性问题,对此各书虽有些论述,但往往不够系统、全面,缺乏分析比较。鉴于α—H在有机化学中的重要地位,我们认为对其进行较深入的探讨是必要的。 In organic chemistry, the carbon atom attached to a functional group is generally called α-C, while the hydrogen atom attached to an α-C atom is called α-H. When studying the nature of organic compounds, α-H is often encountered due to reactivity problems. Although some of these books are discussed, they are often not systematic, comprehensive and lack of analysis and comparison. In view of the important role of α-H in organic chemistry, we think it is necessary to conduct a more in-depth discussion.
