Characterization of Polyphenols from Plant Materials through Their Silylation and 29Si NMR Spectroscopy - Line Assignment through 29Si, 13C Spin-Spin Couplings
Original language description
The lines in 29Si NMR spectra of silylated polyphenols and some other compounds are difficult to assign owing to the absence of couplings with protons outside the silyl group. The assignment can be derived through small nJ(29Si, 13C) couplings (n > 1). Using a previously described method for measurements of these couplings, the assignment procedure is demonstrated here on three examples of trimethylsilylated phenols: 7-hydroxyflavone, ferulic acid, and quercetin. In some cases the procedure can be usedto identify carbon atoms to which the siloxy groups are attached.
