OXIDATIONS OF BIFUNCTIONAL SUBSTRATES WITH SOLUBLE MANGANESE(IV) PHOSPHATE

摘要

Water-soluble manganese(IV) phosphate which is capable of auto-catalytic oxidation of compounds containing two functional groups, was prepared in 3 M phosphoric acid. The reaction was studied with an ethylene glycol-glycollic aldehyde-glycollic acid-glyoxylic acid sequence of compounds, and a reaction mechanism is proposed. The autocatalytic effect is due to manganese(III), which is in itself much less reactive to these substrates. The reaction order of 0.5 related to manganese(IV) can be explained by the existence of binuclear complexes. [References: 27]
