    Selective solid-state photorearrangement through the less stable of two possible biradical intermediates
    摘要:
    The photochemistry of methyl 2-benzoyl-1,4-dihydro-1,4-ethenonaphthalene-3-carboxylate is completely medium-dependent. In solution, two primary di-pi-methane-type photoproducts are formed. Neither of these products is produced when the photolysis is carried out in the solid state; instead, three new photoproducts are formed. The results are interpreted as being due to reaction through 1,3-biradical intermediates, the more stable of which are preferred in solution whereas the less stable ones are formed in the solid state as a result of topochemical restrictions of molecular motion. X-ray crystallographic evidence in support of these ideas is presented and discussed.

    摘要:
    溴化 2,3-二苯甲氧基苯并三氢萘产生二溴化物的区域和立体特异性,这是由芳基转移引起的,其中溴仅从双键的外表面攻击双键。该化合物的高温溴化产生芳基转移产物。从低温溴化2,3-二氰基与重排产物一起获得了苯并戊烯,未重排产物。出乎意料的是,我们观察到未重排产物的产率随温度升高而降低。使用DFT计算模型化合物讨论了取代基的可能作用。

  • Low and high temperature bromination of 2,3-dicarbomethoxy and 2,3-dicyano benzobarrelene: unexpected substituent effect on bromination

    The bromination of 2,3-dicarbomethoxy benzobarrelene yielded the dibromide regio- and stereospecifically arising from the aryl shift where the bromine exclusively attacks the double bond from the exo face of the double bond. High temperature bromination of this compound yielded aryl-shift products. From the low temperature bromination of 2,3-dicyano benzobarrelene, non-rearranged products were obtained

    Benzobicyclo[2.2.2]octatrienes bearing electron-withdrawing groups such as ester and cyano groups on one of the olefin moieties showed anti-facial preference toward oxidative electrophiles in epoxidation and dihydroxylation. The magnitude of the selectivity changed significantly upon aromatic nitration.

  • Substituent effects on the efficiencies and regioselectivities of the di-π-methane rearrangement of vinyl-substituted bicyclic systems
    作者:Helfried Hemetsberger、Matthias Nobbe

    - which were mono- or disubstituted at the vinyl moiety were synthesized. The substituent effects on the efficiencies and regioselectivities of the di-π-methane rearrangement were studied with the results: 1) The dihydrobenzobarrelene system rearranges less efficiently than the 7,7-benzonorbornadiene system. 2) The effect of the substituents on the efficiencies is more pronounced in the less efficient
    Dihydrobenzobarralenes -和7,7- dimethylbenzonorbornadienes -合成了在乙烯基部分被单或双取代的化合物。研究了取代基对二-π-甲烷重排效率和区域选择性的影响,结果表明:1)二氢苯并三氢戊烯烯系统的重排效率低于7,7-苯并降冰片二烯系统。2)在效率较低的二氢苯并barrelene系统中,取代基对效率的影响更为明显。3)如果取代基的自由基稳定作用较大,则效率较高。但是,取代基提高体系间穿越至起始材料基态的速率的作用降低了效率。4)通过取代基的自由基稳定作用控制区域选择性。5)在双取代系统中,第二个取代基有助于提高效率。
