摘要：

以4,4,5,5-四甲基-1,3,2-二氧硼戊环分子为研究对象,对碳硼烷类化合物的核磁共振(NMR)检测方法进行了研究.除了采用常规的核磁共振碳谱(¹³C NMR)、氢谱(¹H NMR)及其二维相关谱外,引入核磁共振硼谱(¹¹B NMR)与二维异核多量子相关谱(¹H-¹¹B HMQC),对含硼类化合物结构进行了测定,该方法对于准确解析硼烷类化合物的结构具有较好的参考意义.

Abstract:

The NMR detection methods for borane-containing compounds were studied, using 4,4,5,5-tetramethyl-1,3,2-dioxaborolane as an example. We showed that the ¹¹B-NMR spectrum of 4,4,5,5-tetramethyl-1,3,2-dioxaborolane can be assigned by combining the information provided byone-dimensional boron spectrum and two-dimensional heteronuclear multiple quantum coherence spectroscopy ¹H-¹¹B HMQC. It is concluded that the methods presented can be used to obtain information of boron atom structure, and to analyze structures of borane-containing compounds.

Key words: ¹¹B-NMR, 4,4,5,5-tetramethyl-1,3,2-dioxaborolane, ¹H-¹¹B HMQC, structure analysis
