Abstract
The1H,13C, and29Si NMR spectra of S-substituted furfurals and the corresponding diethyl acetals containing various alkylsilyl substituents at position S of the furan ring were studied in comparison with the carbon- and sulfur-containing analogs and also with a series of monosubstituted silylfurans. In cases where the substituent was conjugated with the residue of the furan molecule the effect of the substituent at position S of the furan was transmitted to Cα of the aldehyde group. The reverse effect was also observed. It was determined that the contribution from the aldehyde group and the substituents at position S of the furan to the screening of the carbon nuclei of the furan ring was not additive.
