AbstractOxidative C‐2 olefination of indoles/pyrrole via rhodium(III)‐catalyzed direct CH bond activation is reported. Phenolic OH and aniline NH2 units were revealed to be effective chelating groups to activate the aryl CH bond. The reactions proceeded with excellent selectivity and high functional group tolerance, furnishing 2‐vinylindoles/2‐vinylpyrroles in good yields.magnified image

Hydroxyphenylbenzazole compounds that are useful for the selective detection of zinc, aluminum, chromium, and iron cations in vitro and in vivo. The Hydroxyphenylbenzazole compounds include a 2-hydroxyphenyl group bound to a single benzazole group; a first ligand group that is a Schiff base moiety; and a second ligand group selected from a Schiff base moiety and a hydroxyl group
