, p. 973 - 978 (2007/10/02)
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
ASSIGNMENT OF 29Si NMR LINES AND DETERMINATION OF 29Si-13C COUPLING CONSTANTS IN PERTRIMETHYLSILYLATED LIGNIN-RELATED PHENOL-CARBOXYLIC ACIDS BY SELECTIVE HETERONUCLEAR INADEQUATE METHOD

Selective heteronuclear (Si-C) INADEQUATE method has been successfully used to assign all 29Si chemical shifts in six pertrimethylsilylated lignin model compounds.Empirical assignment of the lines in the region δ=23-25 to trimethylsilyl esters of carboxyl
