Abstract

The process of nucleophilic substitution of the phenyliodonium substituent in the [1-B₁₀H₉IPh]^– anion with primary amines in organic nitriles has been studied. It has been shown that the reaction proceeds with the formation of a mixture of products, namely, 1-monoalkylammonio-closo-decaborate and the corresponding amidine, which is formed when an amine molecule is added to the nitrile. The resulting products have been characterized by ¹H, ¹¹B, ¹³C NMR spectroscopies, IR absorption spectroscopy, and high-resolution ESI mass spectroscopy.

取代 1-脒-近十硼酸盐 [1-B10H9NH=C(R1)NHR2]（R1 = Me、iPr、Ph；R2 = nBu、Bn）的合成新方法

 抽象的

研究了[1-B ₁₀ H ₉ IPh] ^– 阴离子中的苯基碘取代基与有机腈中伯胺的亲核取代过程。已经表明，该反应随着产物混合物的形成而进行，即1-单烷基铵-近十硼酸盐和相应的脒，其是在将胺分子添加到腈时形成的。所得产物通过 ¹ H、 ¹¹ B、 ¹³ C NMR光谱、IR吸收光谱和高分辨率ESI质谱进行表征。
