    摘要:
    被在γ位上带有杂原子基团(羟基,烷氧基,卤素,二烷基氨基)或苯基的烃链取代的烯丙基化合物的质谱表现出与C 2 H 4损失相对应的强峰(28a.mu)来自分子离子。这通常是光谱的基峰,这是由于杂原子或苯基基团向中心烯丙碳原子的麦克拉费蒂型转移。在这种过程中,甲基显示出较低的迁移能力。在γ-卤素和γ-羟基酮,烯烃,炔烃或芳烃的光谱中未观察到涉及杂原子基团迁移的这种类型的断裂,并且似乎是烯丙基键的特征。提出了杂原子基团(或苯基)对中心烯丙基碳原子的亲核攻击。

  • Spectres de masse de composes alleniques—I

    heteroatomic group (hydroxy, alcoxy, halogen, dialkylamino) or a phenyl in the γ position exhibits a strong peak corresponding to the loss of C2H4 (28a.m.u.) from the molecular ion. This is commonly the base peak of the spectra and due to a McLafferty type transfer of the heteroatom or phenyl group to the central allenic carbon atom. The methyl group shows a lower migratory aptitude in such a process. This

  • Dye-sensitized photooxygenation of 2,3-dihydrothiophenes: formation of stable 1,2-dioxetanes from 4,5-dialkyl-substituted derivatives
    作者:Klaus Gollnick、Karen Knutzen-Mies
    DOI:10.1021/jo00012a041
    日期:1991.6
    Singlet oxygen reacts with 4,5-dimethyl- (1a), 4-ethyl-5-methyl- (1b), and 4-isopropyl-5-methyl-2,3-dihydrothiophene (1c) to give 1,2-dioxetanes 2a-c in high yields (> 90%). 2a-c represent the first examples of sulfur-substituted dioxetanes that could be isolated. Less than 5% of allylic hydroperoxides 3a, 4a, and 3b, identified by their H-1 NMR spectra, and less than 5% of S-oxides 5a-c were formed in competing ene reactions and sulfoxide-producing steps, respectively. Due to its decreased rigidity, dioxetane 2a is less stable than its oxygen counterpart. Increased flexibility of dioxetanes derived from dihydrothiophenes and dihydrothiopyrans, as compared to those derived from dihydrofurans and dihydropyrans, causes dioxetanes 9 and 16, obtained from 4-carbomethoxy-5-methyl-2,3-dihydrothiophene (8) and 5,6-dimethyl-3,4-dihydro-2H-thiopyran (14), to cleave into dicarbonyl compounds readily at low temperatures. Sulfur-substituted allylic hydroperoxides are also less stable than their oxygen counterparts. Formation of the expected endocyclic allylic hydroperoxides 3a, 3b, and 10 is inferred from the appearance of their H2O2 elimination products, thiophenes 7a, 7b and 13, respectively.
