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.
