Abstract

The reaction of a number of nitrilium derivatives of the closo-decaborate anion with hexamethylene- and nonamethylenediamine has been studied. It has been shown that the process proceeds with the functionalization of both amino groups of the nucleophile to form amidines of the type (Bu₄N)₂[B₁₀H₉NH=C(R)NH (CH₂)_nNH(R)C=NHB₁₀H₉] (R = CH₃, C₂H₅, ⁿC₃H₇; n = 6, 9). Target compounds have been characterized by high resolution multinuclear NMR and ESI mass spectrometry.

摘要

已经研究了许多近十硼酸根阴离子的腈衍生物与己二胺和九亚甲基二胺的反应。已经表明，该过程随着亲核试剂的两个氨基的官能化而进行，形成 (Bu ₄ N) ₂ [B ₁₀ H ₉ NH=C(R)NH (CH ₂ ) _n NH(R )C=NHB ₁₀ H ₉ ](R=CH ₃、C ₂ H ₅、ⁿ C ₃ H ₇；n =6、9)。目标化合物已通过高分辨率多核 NMR 和 ESI 质谱进行了表征。
