A series of new bowl‐shaped N‐hydroxyimide derivatives has been designed and used as selective organoradical catalysts. A number of these bowl‐shaped N‐hydroxyimide derivatives exhibit excellent site‐selectivity in the amination of benzylic C(sp3)−H bonds in aromatic hydrocarbon substrates.

A simple, iron-based catalytic system allows for the inter- and intramolecular arylation of unactivated secondary alcohols. This transformation expands the substrate scope beyond the previously required activated alcohols and proceeds under mild reaction conditions, tolerating air and moisture. Furthermore, the use of an enantioenriched secondary alcohol provides an enantioenriched product for the intramolecular reaction, thereby offering a convenient approach to nonracemic products.

The reactivity of alkyl-substituted cyclohexylbenzenes in liquid-phase oxidation was estimated by the k(2)/root k(6) Value which considerably decreased as the number of methyl groups in the substrate molecule increased. The observed difference in the reactivity of the title compounds was attributed to the degree of coplanarity of intermediate radical species.
