Abstract

Reaction of the potassium salt of nido-carborane with 8-quinolylsulfenyl chloride yielded the 9-(8'-quinolylsulfenyl) derivative of nido-carborane [9‑(НNC₉H₆-8'-S)-7,8-C₂B₉H₁₁], treatment of which with a base yielded the anionic derivative [9-(NC₉H₆-8'-S)-7,8-C₂B₉H₁₁]^–. Complexation of the obtained compounds with [Ni(PPh₃)₂Cl₂] resulted in the formation of the 18-electron half-sandwich nickelacarborane of η⁵,k¹-type [3-PPh₃-3-(4-NC₉H₆-8'-S)-closo-3,1,2-NiC₂B₉H₁₀]. The proposed structures of the obtained nido-carborane derivatives and the metal complex were confirmed by NMR, IR, and UV spectroscopy, as well as mass spectrometry. The electrochemical properties of the synthesized nickelacarborane [3-PPh₃-3-(4-NC₉H₆-8'-S)-closo-3,1,2-NiC₂B₉H₁₀] were studied by cyclic voltammetry.

7,8-二甲酰壬二酸酯9-（8′-喹啉亚砜基）衍生物的合成及其半夹层镍（II）配合物的合成

硝基碳硼烷钾盐与8-喹啉亚砜酰氯反应生成硝基碳硼烷的9-（8′-喹啉亚砜基）衍生物[9‑（НNC9H6-8′- s）-7,8- c2b9h11]，与碱处理得到阴离子衍生物[9‑（NC9H6-8′- s）-7,8- c2b9h11] -。得到的化合物与[Ni(PPh3)2Cl2]络合形成了η5，k1型[3-PPh3-3-(4-NC9H6-8′-s)- close -3,1,2- nic2b9h10]的18电子半夹心镍硼烷。通过核磁共振、红外光谱、紫外光谱和质谱分析证实了所制得的烯碳烷衍生物和金属配合物的结构。用循环伏安法研究了合成的镍碳硼烷[3-PPh3-3-(4-NC9H6-8′- s)- close -3,1,2- nic2b9h10]的电化学性能。
