A minor species , generated by CH activation of the methyl group of CH 3 ReO 3 on reactive surface sites of alumina, is the active site of alumina‐supported CH 3 ReO 3 , a highly active olefin metathesis catalyst, while the major species, formed by coordination of CH 3 ReO 3 at the same sites, is inactive (see scheme; O s denotes the O atoms of the alumina surface).
