  在四甲基间二苯醚中添加氧气

  摘要：

  研究了在各种条件下向四甲叉二茂铁中添加大气氧的情况。通过在THF中将六甲基间环三锗烷光解而制备的二茂铁中添加氧，干净地得到3,3,4,4-四甲基1-3,4-二茂铁氧杂环丁烷（7）。在环境气氛下，在三乙基硅烷存在下，六甲苯基环三锗烷在甲苯中的光解产生了非常复杂的产物混合物，其中有2,2,4,4-四甲苯基-1,2,4-二茂铁氧杂环丁烷（9），四茂基二茂铁环氧乙烷（10）和2分离并鉴定了2,4,4,5,5-己二酰1,2,4,5-trigermadioxolane（11）。化合物9和11的结构通过X射线晶体学确定。

  Germene 1 reacts with the CO and CS double bonds respectively of phenylisocyanate and methylisothiocyanate by formal [2+2] cycloadditions, leading to four-membered ring derivatives 2 and 3. With CS2, dithiagermolane 11 and dithiadigermetane 12 are obtained; the first step of this reaction is probably a formal [2+2] cycloaddition between the GeC and CS double bonds. With nitromethane, oxazadigermolidine

  The germene Mes(2)Ge=CR2 (1, CR2 = fluorenylidene) shows varied behavior toward nitriles. It reacts as a 1,2-dipole with t-BuCN giving a four-membered ring heterocycle, 2-aza-3-germacyclobut-1-ene, as a 1,4-dipole with PhCN, leading to a six-membered ring heterocycle, 3,4-dihydro-3-germaisoquinoline, and as a base, abstracting the alpha-H of R'CH2CN to give alpha-cyanogermanes (R' = H, 2-thienyl, 2-FC6H4, 4-FC6H4).

  Germyl derivatives of N-2,4,6-trifluoroaniline were synthesized either by dehydrohalogenation between halogermanes and 2,4,6-trifluoroaniline over DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) or by elimination between halogermanes and 2,4,6-trfluoroanilinolithium. Dimesitylfluorogermyl N-2,4,6-trifluoroanilinolithium stabilized by THF slowly eliminated lithium fluoride leading to 2,4(2,4,6-trifluorophenyl)-1,3-tetramesitylcyclodigermazane, mainly through intermolecular elimination while in the presence of MgBr2 or tBuMgBr the corresponding germa-imine was formed. Dimesitylchlorogermyl-2,4,6-tritluoroanilino lithium also led to cyclodigermazane while the corresponding bromogermyl lithium or magnesium compound gave mainly the stable 2,4,6-trifluorophenyl dimesitylgerma-imine by intramolecular elimination. The same stable germa-imine was also obtained by exchange reaction between dichlorodimesitylgermane and N-bis(triethylgermyl)2,4,6-trifluoroaniline. Reactivities of monomeric germa-imine and its dimer cyclodigermazane are compared. The dimer is almost inert towards water and methanol and does not react with chloroform and N-tert-butylphenyl nitrone while the germa-imine leads to the corresponding adducts. The adduct with chloroform through alpha-elimination of dichlorocarbene gave N-dimesitylchlorogermyl trifluoroaniline. The electron withrawing effects of the trifluorophenyl group on nitrogen stabilize the germa-imine, preventing its dimerization, but also induce a decrease in reactivity of germanium nitrogen compounds within the series.

  Dimesitylfluorenylidenegermane (1) reacts with ethylbenzylideneamine (PhCH = NEt) to give, according to a [2 + 2] cycloaddition, the very thermally stable four-membered-ring germaazetidine 2. In contrast, imines with a NH function, such as (diphenylmethylidene)amine (Ph2C = NH), react only as protic reagents. A [2 + 4] cycloaddition is observed with azobenzene, affording 5, which slowly aromatizes to 6 or thermally rearranges to give the [2 + 2] cycloadduct germadiazetidine 7. In the case of nitrosobenzene, only the germanone dimer 17 and imine 9 have been observed, probably via the preliminary formation of transient four-membered heterocycle 15.
