The 13CNMR chemical shifts for 1,3-dithiolane and 13 methyl substituted derivatives are reported. Substituent effects are derived and compared with those for cyclopentanes and 1,3-dioxolanes. The magnitude and variety of the substituent effects are best explained with the aid of a half-chair conformation where the S-1-C-2-S-3 plane passes between C-4 and C-5.
The 60 MHz 1H NMR spectra of seven differently substituted 4,5‐dimethyl‐1,3‐dithiolanes have been recorded and analysed. Configurational assignments are made and conformational aspects are discussed in the light of the spectral parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
