Abstract

Trimethylsilylation followed by recording of ²⁹Si NMR spectra is a useful method for functional group analysis, especially as the ²⁹Si lines can be assigned to a particular group by exact experimental techniques. The low sensitivity of these techniques can be overcome by application of reversed methods employing ¹H-detection. Adaptation of heteronuclear multiple quantum coherence 2D NMR spectroscopy to the measurements of ²⁹Si-¹H correlations is described, and preparatory experiments for winnowing signals of protons coupled to a ²⁹Si nucleus are presented. The winnowing experiments designed to optimize 2D experiments have a wider application in identifying the signals of protons that are geminal to the functional group.
