In aqueous media (pH 2.5 -6.0), the Mn IV tetramer [Mn 4 (m-O) 6 A C H T U N G T R E N N U N G (bipy) 6 ] 4+ (1 4+ ; bipy = 2,2'-bipyridine) oxidizes both glyoxylic and pyruvic acid to formic and acetic acid, respectively, under formation of CO 2 . Kinetics studies suggest that the species 1 4+ , it
