Abstract

Bis(diphenylphosphanyl)amine (1), the disulfide 1S and diselenide 1Se were selected to show the efficient application of the INEPT-HEED pulse sequence for measuring coupling constants 1 J(31 P,31 15N) and isotope induced chemical shifts 1 Δ14/15N(31P), both at natural abundance of 15N, from 31P NMR spectra. The sign of 1 J(31P,15N) (> 0) in all three compounds was determined by selective heteronuclear 1H{31P} double resonance experiments.
