    A series of Se-aryl carboselenothioates 3 (RCSSeAr, R=alkyl, aryl) were synthesized and characterized from the reaction of bis(thioacyl) sulfides 1 with sodium areneselenolates. The thionselenolesters 3 are stable (liquid or crystals) both thermally and to moisture. Reactions of 3 with aliphatic primary and secondary amines gave the corresponding ammonium carbodithioates 8 together with diphenyl diselenide

    isolated where L1–L3 loses one proton to provide 3 electrons to metal and alkyne is reduced to olefin. If L4 and L5 are used, products 4a or 4b are generated where the Bronsted acid is not observed but the alkyne is reduced to sp3 and forms a five-membered ring with Co center. Allenes (L6 and L7) lead to 5a(L6) and 5a(L7) where an allyl unit is coordinated to metal. In case of CpH (L8), compounds 6a and 6b

  • Reactivity of 16-electron half-sandwich cobalt compounds containing a chelating 1,2-dicarba-closo-dodecaborane-1,2-dithiolate ligand towards methyl propiolate and dithio ligands

    The reaction of the 16-electron half-sandwich complex MeCpCo(S2C2B10H10) (1b; MeCp = methylcyclopentadienyl) and methyl propiolate (HCCCO2Me) at ambient temperature leads to MeCpCo(S2C2B10H9)(CHCHCO2Me) (2), MeCpCo(S2C2B10H8)(CHCHCO2Me)2 (3), MeCpCo(S2C2B10H9)[MeO2CCCH(MeO2C)CCH)](CHCHCO2Me) (4) and MeCpCo(S2C2B10H9)(CH2CCO2Me) (5). The reaction of Me4CpCo(S2C2B10H10) (1c; Me4Cp = tetramethylcyclopentadienyl) and the alkyne gives rise to Me4CpCo(S2C2B10H10)[MeO2CCCH(MeO2C)CCH] (6) and Me4CpCo (S2C2B10H9)(CH2CCO2Me) (7). Both 2 and 3 are 16-electron complexes but containing a B(3)-substituted o-carborane-1,2-dithiolate ligand in 2 and a B(3,6)-disubstituted o-carborane-1,2-dithiolate ligand in 3, respectively. In 4 and 6, two alkynes are inserted into one Co–S bond to meet an 18 electron configuration at metal, however, 4 has one B-substitution at carborane. Both 5 and 7 have the same structural type bearing a B–CH2 unit. The reactions of Cp#Co(E2C2B10H10) [Cp# = Cp (1a), MeCp (1b), Me4Cp (1c) and Me5Cp (1d); E = S, Se] with 2-methylpropanedithioic acid (L1) or pyrrolidine-1-carbodithioic acid (L2) lead to Co[S2CCH(CH3)2]3 (8) or Co[S2CN(CH2)4]3 (9), respectively, in an octahedral geometry. The three-component reactions of 1a–1d, methyl propiolate and L1 or L2 afford seven new compounds Cp#Co[S2C2B10H10(CHCHCO2Me)][S2CCH(CH3)2] [Cp# = Cp (10a), MeCp (10b) and Me4Cp (10c)], [S2CCH(CH3)2]2Co(S2C2B10H10)(CHCCO2Me)CpCo[S2CCH(CH3)2]} (11a), Cp#Co[S2C2B10H10(CHCHCO2Me)][S2CN(CH2)4] [Cp# = Cp (12a), MeCp (12b) and Me4Cp (12c)]. All 10a–10c and 12a–12c contain one deprotonated L1 or L2 ligand and one reduced alkyne. 11a has two 18-electron Co centers linked by one reduced alkyne. One metal is coordinated by an o-carborane-1,2-dithiolate and two L1 ligands, and the other is coordinated by one L1 ligand and one η5-Cp unit. In both two- and three-component reactions the reactivity of the 16-electron half-sandwich complexes Cp#Co(S2C2B10H10) is dependent on the size of the Cp# unit. All compounds were fully characterized by spectroscopic techniques and elemental analysis. The solid-state structures of 4, 5, 7, 10a and 11a were further determined by X-ray crystallographic analysis.
    16电子半三明治配合物MeCpCo(S2C2B10H10) (1b; MeCp = 甲基环戊二烯基)与甲基丙炔酸酯(HCCCO2Me)在室温下反应,生成MeCpCo(S2C2B10H9)(CHCHCO2Me) (2)、MeCpCo(S2C2B10H8)(CHCHCO2Me)2 (3)、MeCpCo(S2C2B10H9)[MeO2CCCH(MeO2C)CCH](CHCHCO2Me) (4)和MeCpCo(S2C2B10H9)(CH2CCO2Me) (5)。Me4CpCo(S2C2B10H10) (1c; Me4Cp = 四甲基环戊二烯基)与炔烃的反应生成Me4CpCo(S2C2B10H10)[MeO2CCCH(MeO2C)CCH] (6)和Me4CpCo(S2C2B10H9)(CH2CCO2Me) (7)。2和3均为16电子配合物,但2中含有B(3)-取代的o-硼烷-1,2-二硫配体,而3中含有B(3,6)-二取代的o-硼烷-1,2-二硫配体。在4和6中,两种炔烃插入一个Co–S键,以达到金属的18电子构型,但4在车伯烷上有一个B取代。5和7具有相同的结构类型,含有B–CH2单元。Cp#Co(E2C2B10H10) [Cp# = Cp (1a)、MeCp (1b)、Me4Cp (1c)和Me5Cp (1d); E = S, Se]与2-甲基丙烯二硫酸(L1)或呋喃-1-羧基二硫酸(L2)的反应分别生成Co[S2CCH(CH3)2]3 (8)或Co[S2CN(CH2)4]3 (9),呈八面体几何结构。1a–1d、甲基丙炔酸酯及L1或L2的三组分反应生成七个新化合物Cp#Co[S2C2B10H10(CHCHCO2Me)][S2CCH(CH3)2] [Cp# = Cp (10a)、MeCp (10b)和Me4Cp (10c)]、[S2CCH(CH3)2]2Co(S2C2B10H10)(CHCCO2Me)CpCo[S2CCH(CH3)2]} (11a)以及Cp#Co[S2C2B10H10(CHCHCO2Me)][S2CN(CH2)4] [Cp# = Cp (12a)、MeCp (12b)和Me4Cp (12c)]。所有10a–10c和12a–12c均包含一个去质子化的L1或L2配体和一个还原的炔烃。11a具有两个18电子的Co中心,通过一个还原的炔烃连接。一个金属由一个o-硼烷-1,2-二硫配体和两个L1配体配位,另一个由一个L1配体和一个η5-Cp单元配位。在两组分和三组分反应中,16电子半三明治配合物Cp#Co(S2C2B10H10)的反应性取决于Cp#单元的大小。所有化合物均通过光谱技术和元素分析进行了充分表征。4、5、7、10a和11a的固态结构进一步通过X射线晶体学分析确定。
