  摘要：

  The bis(boratabenzene)scandium complexes 3-5 are synthesized from solvent-free lithium boratabenzenes and ScCl3 in toluene (110 degrees C, 3 days). Complex [ScCl(C5H5BMe)(2)](2) (3) possesses a doubly chloro-bridged dinuclear structure with four facially coordinated boratabenzene ligands. Compound [ScCl(3,5-Me2C5H3BNMe2)(2)](2) (4) differs from 3 in that each scandium atom binds to one boratabenzene in an unprecedented N-B-C-2 coordination mode and facially to the second boratabenzene ligand; in solution 4 is fluxional, displaying only one type of boratabenzene ligand with effective lateral symmetry. Complex ScCl[3,5-Me2C5H3BN(SiMe3)(2)](2) (5) is mononuclear because of the bulkiness of its boratabenzene. Metalation of the 1,2,3,6-tetrahydroborinine 3-CH2-5-MeC5H5BNMe2 (9) affords the solvent-free boratabenzene Li(3,5-Me2C5H3BNMe2) (7). The mixture of 1,2- and 1,4-dihydroborines 3,5-Me2C5H4BNMe2 (10a,b) (accessible from 9 by isomerization) can be transformed into the solvent-free boratabenzene Li[3,5-Me2C5H3BN(SiMe3)(2)] (8) by (i) treatment with BCl3 to give the chloro derivatives 11a,b, (ii) subsequent amination with NH(SiMe3)(2)/NEt3, and (iii) metalation with LiN(SiMe3)(2).

  lithium boratabenzenes Li(3,5-Me2C5H3BNiPr2), Li(3), and Li2[(3,5-Me2C5H3BNMe)2(CH2)2], Li2(5), via the dicarbanion route are described. Lithium 1-aminoboratabenzenes react with metal trihalides in toluene (110 °C, 3 d) to give the stepped ladder dimers [(3,5-Me2C5H3BNMe2)2Y(μ-Cl)2Li]2, (12), [(3,5-Me2C5H3BNMe2)2Lu(μ-Cl)2Li]2 (13), and the mononuclear complexes YCl[3,5-Me2C5H3BN(SiMe3)2]2 (18), LuCl[3,5-Me2C5H3BN(SiMe3)2]2

  描述了通过二碳阴离子路线合成新的硼氢化锂锂 Li(3,5-Me2C5H3BNiPr2)、Li(3) 和 Li2[(3,5-Me2C5H3BNMe)2(CH2)2]、Li2(5)。1-氨基硼酸锂在甲苯中与金属三卤化物反应 (110 °C, 3 d) 得到阶梯式二聚体 [(3,5-Me2C5H3BNMe2)2Y(μ-Cl)2Li]2, (12), [(3, 5-Me2C5H3BNMe2)2Lu(μ-Cl)2Li]2 (13) 和单核配合物 YCl[3,5-Me2C5H3BN(SiMe3)2]2 (18), LuCl[3,5-Me2C5H3BN(SiMe3)2] 2 (19) 和 ScCl(3,5-Me2C5H3BNiPr2)2 (20)。当使用 THF 或 THP 等供体溶剂时，类似的反应会在环境温度下发生，得到溶剂化物，例如 (3,5-Me2C5H3BNMe2)2Sm(μ-Cl)2Li(THF)
