  摘要：

  Hypohalogenation of 2-methylhex-5-en-3-yn-2-ol, 2-methylhept-6-en-3-yn-2-ol, and their methyl ethers at 303-328 K with hydrochloric or hydrobromic acid in the presence of hydrogen peroxide involves only the double bond to produce the corresponding halohydrins in fairly high yields. Kinetic parameters of these reactions were determined, and the allylacetylenic alcohol and its methyl ether were found to be more reactive than their vinylacetylenic analogs. Acetylenic halohydrins and oxiranes derived therefrom were shown to be quite reactive compounds which may be used as building blocks in organic synthesis.

  A comparative study of the Diels-Alder reaction have been carried out for three types of cyclic dienes: cyclopentadiene (CPD), hexachlorocyclopentadiene (HCP), and tetrachloro-1,2-benzoquinone (TCBQ) with dienophiles of five types: monosubstituted acetylenes (propargyl alcohol and its esters), conjugated amines (allyl acetylene, allyl ethynyldimethylcarbonol and its esters), conjugated dienes (2-methylhexadiene-3

  已对三种类型的环状二烯进行Diels-Alder反应的比较研究：环戊二烯（CPD），六氯环戊二烯（HCP）和四氯-1,2-苯醌（TCBQ）与五种亲二烯体：单取代乙炔（炔丙醇及其酯），共轭胺（烯丙基乙炔，烯丙基乙炔基二甲基碳醇及其酯），共轭二烯（2-甲基己二烯-3,5-ol-2及其酯，1-乙氧基和1-乙氧基羰基丁二烯-1,3 ）和共轭三烯（hexatriene-1,3,5 and 5-methylhexatriene-1,3,5）。

  Diels-Alder reactions of 1,2,3,4-tetrachloro-, 1,2,3,4-tetrachloro-5,5-dimethoxy-, and hexachlorocyclopentadienes with vinyl- and allylacetylene dienophiles were studied. Kinetic parameters of these reactions were determined, and the cycloaddition processes were assigned to the "neutral" type involving symmetric arrangement of the highest occupied and lowest unoccupied molecular orbitals of the diene and dienophile. Vinylacetylene derivatives were found to be more reactive than allylacetylenes. Increase in the number of chlorine atoms in the bicycloheptene fragment of the adduct favors its acetylene-allene isomerization.
