Abstract

Abstract N-Trimethylsilylaminophosphorus compounds containing phosphorus in different oxidation states [P (III) and P (V)] and with different coordination numbers (2, 3 or 4) were studied by 13 C, 14 N, 29 Si and 31 P NMR, using a variety of one-and two-dimensional (2D) techniques, including Hahn-echo extended (HEED) pulse sequences. These techniques were demonstrated by the determination of the signs of all coupling constants ...
