Carbon 13 NMR Spectra of Dimethyl Fumarate and its Thioderivatives: Empirical Shielding Constants for the Methyl Ester and Thioester Substituents†

Abstract

The assigned ¹³C NMR spectroscopic data from O,S-dimethyl thiofumarate, S,S-dimethyl bis(thio)fumarate and the novel S-methyl p-methoxythiocinnamate are presented and the empirical shielding constants for the methoxycarbonyl and methylsulfanylcarbonyl groups determined for the first time.
