Abstract

Abstract New phosphinoamides, chalcogenides, and amidophosphates were synthesized and characterized by 1 H, 13 C, 31 P NMR, IR spectroscopy, and elemental analysis. The 13 C NMR spectra of two phosphinoamides exhibit obvious differences between their 1 J (P, C) coupling constants (128.3 Hz in one compound vs. 439.2 Hz in another compound). Natural bond orbital analysis was performed to clarify the electronic behavior of the title molecules ...
