The 15 N NMR spectra of ten isocyanates, four isothiocyanates, and four N ‐sulfinylamines have been obtained at the natural‐abundance level by high‐resolution NMR spectroscopy. The results show that isocyanates and isothiocyanates have 15 N chemical shifts over 200 ppm toward higher fields compared to those of N ‐sulfinylamines. The sensitivity of the 15 N shifts in these substances to substituent and electronic effects are discussed.
