Abstract

Prepg. quinoxaline-1,4-dioxide (I) comprises oxidising quinoxaline (II) with aq. 10-70 wt.% H2O2 in presence of a Mo (VI) cpd. (III), e.g. molybdic acid anhydrides. (I) is used as a feed additive to stimulate growth of animals for slaughter. Use of toxic W catalysts is avoided; Mo is not toxic to animals even at doses of 1-6g/kg. Yields are better than 70%.
