Abstract

New orange solid dabco ammonium halochromates, \( {\text{C}}_{6} {\text{H}}_{14} {\text{N}}_{2}\,^{ + } \) \( {\text{Cr}}_{2} {\text{F}}_{2} {\text{O}}_{6}\,^{ - } \), DAXC (X = F, Cl) are easily synthesized by the reaction of dabco (1,4-diaza-bicyclo[2.2.2] octane) with CrO3 in a 1:2 molar ratio in the presence of HF or HCl. Dabco ammonium halochromates(VI) are versatile reagents for the effective and selective oxidation of organic substrates to carbonyl derivatives.
