\nRésumé : After a brief mention of our original hyd
 rogenation catalyst from the 1970s\, we move on to recent work in the titl
 e areas. A number of organoiridium-based catalyst precursors prove highly 
 active for water oxidation driven either by electrolysis or by chemical ox
 idants. The active resting state species is found to be a coordination com
 plex with a Ir(IV)—O—Ir(IV) core. This material binds irreversibly to 
 oxide surfaces with full retention of catalytic activity. The same catalys
 t\, applied to alkane oxidation\, produces hydroxylation with retention of
  configuration at carbon\, consistent with an oxene-like insertion mechani
 sm. Related catalysts that bring about alcohol dehydrogenation have been a
 pplied to conversion of the biodiesel residue\, glycerol\, to lactic acid.
