Abstract

The NMR spectra of a series of sodium alkane-1-sulphonates and sodium 1-hydroxyalkane- 1-sulphonates show that the two systems may be characterised by the-CH2SO3-and-CH (OH) SO3− resonance signals at δ= ca. 2.85 and ca 4.4 ppm, respectively. Analysis of the NMR spectra of the bisulphite adducts formed by α, β-unsaturated aldehydes confirms the earlier structural assignments of the 1, 3-disulphonic acid salts. The NMR spectra of the 1: ...
