Iridium compounds are used as catalysts in the Cativa process for carbonylation of methanol to produce acetic acid. [92] [93] Iridium complexes are often active for asymmetric hydrogenation both by traditional hydrogenation. [94] and transfer hydrogenation. [95] This property is the basis of the industrial route to the chiral herbicide (S ...
All element articles and their infoboxes use IUPAC spelling of elements and compounds. Notably, that is aluminium, sulfur, caesium , not aluminum, sulphur, cesium . For other English variant words (vapor vs. vapour) the infobox reads |engvar= .
