摘　　要：以4,4,5,5-四甲基-1,3,2-二氧硼戌环分子为研究对象,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(^(13)C NMR)、氢谱(~1H NMR)及其二维相关谱外,引入核磁共振硼谱(^(11)B NMR)与二维异核多量子相关谱(~1H-^(11)B 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-l,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 ofborane-containing compounds.
