    摘要:
    八氯环庚三烯,C7Cl8,与多种有机金属前体反应,例如Fe2(CO)9,Co2(CO)8,[(C5H5)Fe(CO)2] -,产生十二氯七氟烯,C14C12,12,收率为54%至68%。没有证据支持C7Cl6 = MLn这种类型的卡宾配合物的中间体存在,因此建议反应通过C7Cl8的脱氯反应进行,从而产生六氯环戊烯,其二聚体形成观察到的产物。扩展的Hückel分子轨道计算用于表明氯化卡宾C7Cl6应比相应的母体系统C7Cl6更稳定。EHMO计算还显示,平面七氟烯在电子上不受欢迎,应该优先以S-anti构象存在,就像C14H12一样。X射线晶体学显示,分子C14Cl12,12仅以同构体形式形成,其在高温下异构化为反式结构。 12中的两个七元环的构象与八氯环庚三烯本身非常相似。C7Cl8,3以正交晶系空间群Pnma结晶,a = 7.140(1)Å,b = 13.329(3)Å,c = 12.595(3)Å,V = 1198.7(4)Å3,Z = 4.3采用严重弯曲的船型结构,其中平面C(1)-C(7)-C(6)和C(2)-C(3)-C(4)-C(5)分别与C(1)-C(2)-C(5)-C(6)平面成51.8°和32.4°的角度。关键词:八氯环庚三烯,七氟烯,金属介导的二聚化。

  • Reactions of Dimethoxycarbene with Cyclic Perchlorinated Olefins and Ketones
    作者:James A. Dunn、John Paul Pezacki、Michael J. McGlinchey、John Warkentin

    日期:1999.6.1
    Reactions of dimnethoxycarbene (2), a carbonyl group equivalent, with perchlorinated olefins and ketones were investigated. Thermolysis of 2,2-dimethoxy-5,5-dimethyl-Delta(3)-1,3,4-oxadiazoline (1) at 110 degrees C generated 2, which reacted with hexachlorocyclopentadiene (4), octachlorocycloheptatriene (12), octachlolobicyclo[3.2.0]hepta-3,6-diene (24), hexachlorotropone (28), hexachlorobicyclo[3.2.0]-hepta-3,6-dien-2-one (32), and tetrachloro-1,4-benzoquinone (35). Reactions of 2 with perchlorinated olefins 4, 12, and 24 led to esters or, in the case of 12, to a ketene acetal. Their formation is rationalized in terms of Michael-like addition and displacement (S(N)2' or S(N)2", if concerted) of allylic chlorine atoms by 2, yielding ion pairs that either dechloromethylate to esters or dechlorinate to a ketene acetal, In contrast, the reactions of 2 with unsaturated perchloroketones 28, 32, and 35 led to ring contraction, ring expansion, and aromatization, respectively. The products from these reactions are consistent with nucleophilic addition of 2 at the carbonyl moiety rather than Michael-type addition. Dimethoxycarbene-d(3) was used to show that demethylation in the latter reaction was intermolecular. Mechanisms for the different reaction courses are proposed.
