Abstract

Abstract: Four methods have been developed to prepare aquachromium (IV), which we believe to be an oxo ion, CrOZ+. It readily converts Ph3P to Ph3P0 (k= 2.1 X lo3 L mol-'SI) at 25 OC in 85% CH3CN/H20 (0.10 M HC104). The reactions used to form GO2+ are those between Cr2+ and (a) O2 (b) anaerobic Cr022+,(c) anaerobic CrOOCr4+, and (d) anaerobic TI (II1). The Cr02+ has a half-life of 30 s in acidic solution at room temperature and will ...
