  摘要：

  Hexachloronorbornadiene efficiently forms a 1:1 adduct 3 with 5,6-bismethylenenorbornene. Adduct 3 on reaction with 1,2,3,4-tetrachlorothiophene dioxide (TCTD) under mild conditions gives an SO2 bridged adduct, which loses SO2, the product cycloreverting to give 1,2,3,4-tetrachlorobenzene and an annelated cyclopentadiene 8; 8 reacts further with TCTD to give, in 1:1 ratio, two compounds (14 and 15) shown by mass, C-13 and H-1 NMR spectroscopy and single crystal X-ray structure determination to be the stereoisomeric products of a rare type of specific diene capture by TCTD. Evidence is presented that this result (and analogous examples) is best understood in terms of ''normal'' [4+2]pi cycloadditions to 8 as dienophile towards electron-deficient TCTD, followed by rapid Cope rearrangement of the SO2-bridged intermediate adducts to give the observed products. At low temperatures adduct 3 behaves as expected towards electron-deficient diene tetracyclone ; the [4+2]pi cycloadduct decarbonylates on mild thermolysis, concomitant cycloreversion also giving diene 8. At much higher temperatures in the presence of excess tetracyclone, diene 8 likewise behaves as dienophile; the carbonyl-bridged major cycloadduct decarbonylates to give an intermediate which undergoes an unusual thermally-allowed [pi2s + pi2a + sigma2a] 1,3-shift/cycloaddition, delivering a symmetrical cage-like structure 24, as indicated by mass and C-13 and H-1 NMR spectroscopy.

  摘要：

  六氯诺尔布尔烯与5,6-双亚甲基诺尔布尔烯形成1:1加合物3。当其与1,2,3,4-四氯噻吩二氧化物反应时，通过脱硫氧（SO2）、环逆转和进一步的环加成，生成两种化合物。这些化合物通过质谱、13C NMR和1H NMR光谱以及单晶X射线结构解析被鉴定为一种稀有特定二烯被过氯噻吩二氧化物捕获的异构体产物；对此及其他例子的合理解释被提出，同时还披露了诺尔布烯sp²C金字塔化的进一步实例。
