Abstract

Materials and Methods Commercially available chemicals were obtained with sufficient purity and used as received. Ammonium hypophosphite was recrystallized from water and dried over P 2 O 5. NMR spectra were recorded on a Varian UnityPlus 300 (1 H) spectrometer. For the measurements in D 2 O, t-BuOH was used as an internal standard with the methyl signal referenced to 1.2 ppm (1 H) or 31.2 ppm (13 C). One percent of H 3 PO 4 ...
