The barrier to inversion at arsenic in the title compounds has been shown to exceed 25 kcal mol–1, and a previous report that inversion is rapid in these compounds has thus been invalidated.

localize and quantify the fractional incorporation of 13C isotope into each carbon atom of precursor-derived metabolites. In this paper, several carbohydrate derivatization procedures (peracetylation, deuterioalditol acetates, and aldononitrile acetates) are evaluated for the positional isotopic information obtained by gas chromatography/electron impact mass spectrometry (GC/EI-MS). These derivatives

chemical shifts are given for the complexes formed by 31 different thiolates individually in water at ambient probe temperature, and slow-exchange 1H and/or 13C and/or 113Cd NMR spectra are reported for several typical complexes at reduced temperature in CD3OD. In aqueous solution at ambient probe temperature, ligands with vicinal thiolate groups and −SCH2CHRS− (R = H, Me, Et, CH2OH, CH2SO−3 or CH2S−)) form
