The structure of the products from the reaction of α,β-unsaturated aldehydes and ketones with thiocyanic acid was established by IR and 1H and 13C NMR spectroscopy.It was shown that the addition temperature and the structure of the obtained product depend on the structures of the initial compounds.It was established that the reactions of α,β-unsaturated aldehydes and ketones not containing methyl substituents at the Cβ carbon atom lead to the formation of isomeric β-isothiocyanato and β-thiocyanato carbonyl compounds, whereas the β-isothionato derivatives are formed exclusively in the case of t he β-methyl- and β,β-dimethyl substituted α,β-unsaturated aldehydes and ketones.
