Stereochemistry of peroxoborate ion
網頁Sodium Peroxoborate. Sodium peroxoborate [10332-33-9] ( sodium perborate monohydrate ), Na2 [82 (02)2 (011)4], formerly written as NaBO H20, is known only as a microcrystalline powder, made by dehydrating the hexahydrate. The crystal stmcture has not been deterrnined, but the vibrational spectmm (27) indicates the presence of the same … 網頁The relative intensities of certain ions in the mass spectra of trimethylsilylated pyranoses have been observed to depend on the stereochemistry of the molecule. A system has been developed which is capable of explaining the differences between the anomeric forms of D-glucose, D-galactose, D-mannose and D-xylose.
