Nitrogen-containing aromatic heterocyclic ligand-metal complexes and their use for the activation of hydrogen peroxide and dioxygen are disclosed. Processes whereby activated hydrogen peroxide or dioxygen are used to transform various organic substrates are also disclosed. In particular processes for the conversion of methylenic carbons to carbonyls, for the dioxygenation of aryl olefins acetylenes and aryl-.alpha.-diols, for the oxidation of alcohols and aldehydes and for the removal of mercaptans from gaseous streams and for the removal of hydrogen sulfide and/or mercaptans from liquid streams are disclosed.

Why it's free to use
- Filed January 15, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 15, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 15, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
