Abstract

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
