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.

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.
