ORGANIC CHEMISTRY OF SUPEROXIDE. II OXIDATION OF β-NAPHTHYLAMINE - POSSIBLE INVOLVEMENT OF THE HYDROXYL RADICAL
Crank, G.,Makin, M. I. H.
, p. 3159 - 3160 (1983)
Of a selection of aromatic monoamines examined only β-naphthylamine was oxidized by potassium superoxide and formed dibenzophenazine, dibenzophenazine and 1-hydroxy-2,2'-azonaphthalene, the latter product indicating that the hydroxyl radical may be involved in superoxide oxidations.

A mild procedure for the selective preparation of diverse heterocycles (such as quinoxaline, phenazine, phenothiazine, etc.) from beta-tetralones and nitrogen nucleophiles under metal-free conditions has been developed. The iodine reagents played an important role in the selectivity control of condensation and dehydrogenative aromatization cascade processes. These reaction conditions tolerate a wide range of functional groups and apply to oxidation-sensitive nitrogen nucleophiles. (Figure presented.).

Paragraph 0061; 0062, (2016/11/17)
The invention relates to a novel metal complex and application thereof in an organic luminescent device. The structural general formula of the metal iridium complex for near infrared luminescence is LnIrX(3-n), wherein X is selected from acetylacetone, dibenzoylmethane, dipivaloylmethane or picolinic acid; n is selected from 1, 2 or 3; L is selected from the following structural formula L1, L2 or L3; R1-R9 are independently selected from H, C1-10 alkyl, C1-10 alkoxy, C1-10 alkylamino, carbazolyl, F, trifluoromethyl and C5-18 aryl respectively; and Ar represents C5-18 aryl and C5-18 heterocyclic aryl. The metal complex has the advantages of short luminescence life and high luminescence efficiency; and an organic luminescent device prepared from the luminescent material has the characteristic of high luminescence efficiency under high current density. The structural formula L1, the structural formula L2 and the structural formula L3 are shown in the specification.
Oxidations of Aromatic Amines by Superoxide Ion
Crank, George,Makin, Mohammad I. H.
, p. 845 - 855 (2007/10/02)
Superoxide ion acts as a mild and highly selective oxidizing agent for aromatic amines.Aniline and α-naphthylamine were not oxidized, but β-naphthylamine formed dibenzophenazine, dibenzophenazine and 2,2'-azonaphthalen-1-ol. o- and p-Diamines are oxidized to diaminoazobenzenes but m-diamines are unreactive.Similarly o- and p-aminophenols are oxidized to dihydroxyazobenzenes but m-aminophenols are unaffected, and o-mercaptoaniline forms the disulfide.The oxidations are considered to be free-radical processes, initiated by hydrogen abstraction by superoxide from the substrates.The biological significance of the results is discussed.
