为了通过与银河宇宙射线 (GCR) 的相互作用研究星际冰中醛的烯醇化，我们用高能电子照射乙醛冰，作为在穿透星际冰时在 GCR 轨道中产生的二次电子的代理。 结果表明 GCR 可以诱导乙醛的烯醇化，并且分子内和分子间过程是相关的。 因此，烯醇在星际介质中应该无处不在，可以使用射电望远镜（如 ALMA）进行搜索。 一旦检测到烯醇并确定丰度，它们就可以作为星际冰中非平衡化学的示踪剂，从而最终限制星际冰深处的基本反应机制。 结果表明 GCR 可以诱导乙醛的烯醇 …

2021年4月28日 · To study the enolization of aldehydes in interstellar ices by interaction with galactic cosmic rays (GCRs), we irradiated acetaldehyde ices with energetic electrons as proxies of secondary electrons generated in the track of GCRs while penetrating interstellar ices.

2001年1月6日 · Consistent with the C−O cleavage behavior of vinyl ethers, vinyl fluoride reacts with Cp 2 ZrHCl to give Cp 2 ZrFCl and C 2 H 4 as primary products.

2021年4月28日 · Interstellar Enolization-Acetaldehyde (CH3CHO) and Vinyl Alcohol (H2CCH (OH)) as a Case Study. The results indicate that GCRs can induce enolization of acetaldehyde and that intra- as well as intermolecular processes are relevant and enols should be ubiquitous in the interstellar medium and could be searched for using radio telescopes such as ALMA.

烯丙基是一种 官能团，结构式为：H2C=CH-CH2-。 在化合物中加入烯丙基基团后能产生新的带有烯键的化合物，使原化合物理化性质彻底改变，化合物的烯丙基化广泛应用于有机和药物合成，如具有广泛 生物活性 的光学活性α-氨基膦酸酯衍生物的合成。 另外，-CH=CH-CH3 叫正 丙烯基 （系统命名叫1-丙烯基） —CH2-CH=CH2叫正烯丙基（系统命名叫2-丙烯基）。 芳香化合物 的选择性官能化反应是一类重要的 有机合成 反应，一直受到药物研发、 材料科学 和 精细化工 等 …
