29Si and 13C NMR Spectra of 4-Substituted 2-Methoxytrimethylsiloxybenzenes. Factors Determining the Chemical Shifts in Models of Lignin Constituents

Article abstract of DOI:10.1002/mrc.1260281112

29Si and 13C NMR chemical shifts are reported for a series of twenty 4-substituted 2-methoxytrimethylsiloxybenzenes; the set of substituents incorporates a basic set of ten substituents differing in their relative polar and resonance effects and ten other
