    名称:
    Reactivity, absorption and emission of dimethylgermylene photo-generated from dodecamethylcyclohexagermane
    摘要:
    The UV photolysis of dodecamethylcyclohexagermane (1) in cyclohexane at room temperature proceeds readily with loss of dimethylgermylene species to give two of the lower homologs, decamethylcyclopentagermane (2) and octamethylcyclotetragermane (3). The photochemically generated dimethylgermylene species reacts with 2,3-dimethylbuta-1,3-diene or CCl4 to give 1,1,3,4-tetramethyl-1-germacyclopent-3-ene or trichloromethyldimethylchlorogermane, respectively. The transient absorption of 1 in cyclohexane at 450 nm obtained by laser flash-photolysis is due to dimethylgermylene. The reaction rates of dimethylgermylene with some substances are examined. In 3-methylpentane glass dimethylgermylene shows an absorption band at 430 nm and a fluorescence peak at 650 nm. The photo-generated germylene appears to be the singlet ground state.

    摘要:
    Diphenylgermylene (Ph2Ge) 及其 Ge=Ge 双键二聚体四苯基二锗烯 (6a) 首次通过激光闪光光解方法直接在溶液中表征。锗烯是通过 3,4-二甲基-1,1-二苯基锗环戊-3-烯 (4a) 的(正式)螯合光环回复形成的,这表明其以高化学(> 95%)和量子产率(phi = 0.62)进行) 通过使用甲醇、乙酸、异戊二烯和三乙基硅烷进行稳态捕获实验。4a 在 23 摄氏度干燥脱氧己烷中的闪光光解导致迅速形成分配给 Ph2Ge 的瞬态(λ(最大)= 500 nm;epsilon(最大)= 1650 M(-1)cm(-1)),它以二阶动力学衰减(tau 大约 3 微米),伴随着分配给二锗烯 6a(tau 大约 40 微米;λ(最大)= 440 nm)的第二个瞬态物种的生长。从 1,1-二甲基-和 1,1-二甲基-3,4-二甲基锗环戊-3-烯(分别为 4b 和 4c)获得了类似的结果,它们提供了

    transient bands of tetraalkyldigermenes using nanosecond laser flash photolysis appeared at ca. 380 nm. The rate constants for the quenching reactions of the digermene with oxygen, polyhalomethanes, alcohols, 2,3-dimethylbuta-1,3-diene, 1-hexyne, and triethylsilane were also measured under various conditions. The quenching reactions of digermenes with carbon tetrachloride and ethanol (k = ∼107 M-1 s-1) are

    The reactions of methanol, tert-butanol, and THF with a series of simple germylene derivativesdimethyl- (GeMe2), diphenyl- (GePh2), and dimesitylgermylene (GeMes2; Mes = 2,4,6-trimethylphenyl)have been studied in hexane solution at 25 °C by laser flash photolysis methods. The results are consistent with rapid, reversible reaction to form weakly stabilized Lewis acid−base complexes, which exhibit UV

    Photolysis of 7,8-digermabicyclo[2.2.2]octadiene (I) was studied by means of H-1-CIDNP and laser pulse photolysis techniques. It was found that photodecomposition of I occurs via germanium-centered 1,6-biradical species. 1,4-Diphenylnaghthalene and tetramethyldigermene are the primary products of the photolytic reaction.
