Abstract
The 13C NMR spectra of 1,3‐propanesultam, 2,4‐butanesultam, 1,4‐butanesultam, 1,3‐propanesultone and 1,4‐butanesultone, as well as some of their unsaturated analogs 2,4‐dimethylbuta‐1,3‐diene‐1,4‐sultone and 2,4‐dimethylbuta‐1,3‐diene‐1,4‐sultam, have been recorded. The observed chemical shift data for the sultams and sultones can be explained mainly on the basis of inductive effects. The δ values of the dienesultone and the dienesultam are mainly affected by M‐effects. 1H NMR as well as mass spectra have.Keywords
