Abstrakt:	Tri- tert-butoxyaluminum reacts with tert-butyl hydroperoxide to produce di- tert-butoxy- tert-butyl alumotrioxide, which decomposes heterolytically to form singlet dioxygen and homolytically with the O—O bond cleavage. The ButOO·, (ButO)2AlOO·, ButO·, and (ButO)2AlO· radicals were identified by ESR using spin traps. These findings confirm the formation of aluminum-containing trioxide. The above radicals initiate alkylarene oxidation by the tri- tert-butoxyaluminum— tert-butyl hydroperoxide system. The carbon-centered and alkylperoxy radicals originated from the oxidized substrates were identified. [ABSTRACT FROM AUTHOR]
