| 摘要: 本文以[(Me2)NCH2C6H4CHSiMe2(NMe2)]Li(TMEDA)与叔丁腈为原料按1∶1加成得到氮杂烯丙基的锂化合物[{(Me2)NCH2C6H4}CHC(tBu)NSiMe2(NMe2)Li(TMEDA)]即1。然后用乙醚或四氢呋喃作溶剂化合物1和二氯化亚铁或二氯化钴按2∶1反应得到氮杂烯丙基铁或钴的化合物分别为2和3。通式为M[{(Me2)NCH2C6H4}CHC(tBu)NSiMe2(NMe2)]2(M=Fe (2)，Co (3))。化合物1，2和3的结构分别用 1H NMR，13C NMR，元素分析和X-射线单晶衍射技术进行了表征。晶体结构表明化合物2和3结构类似，都是以金属为对称中心的硅桥联的端基氮配位的氮杂烯丙基化合物。 |

| Abstract: The N-silyl-Ni-1-(2-((dimethylamino)methyl)benzyl)-N,N,1,1-tetramethylsilanamiolithium 1-azaally com-pound [{(Me2)NCH2C6H4}CHC(tBu)NSiMe2(NMe2)Li(TMEDA)] (1) was synthesized by interaction of [(Me2)NCH2C6H4CHSiMe2(NMe2)]Li(TMEDA) with one equivalent of tertbutyronitrile (tBuCN). The derivative iron(Ⅱ) and cobalt(Ⅱ) compounds were produced by the treatment of 1 with FeCl2 or CoCl2 in tetrahydrofuran or diethylether at zero temperature, respectively, with the general formula M[{(Me2)NCH2C6H4}CHC(tBu)NSiMe2(NMe2)]2(M=Fe (2), Co (3)). The 1-azaally complexes 1, 2 and 3 were also characterized by X-ray single crystal diffraction and NMR analysis. Structural analyses of 2 and 3 reveal that their molecular structures are very similar. The structure of the centrosymmetric crystalline Fe(Ⅱ) or Co(Ⅱ) is unusually within the present series of homoleptic metal(Ⅱ) 1-azaallyls in that it is an κ1-enamido metal complex.
