The reactions of 4-alkoxybut-3-en-2-ones with primary aromatic amines and diamines of the aromatic and heteroaromatic series follow analogous schemes. 

The new method of Yoneda s group132 is also a one-pot diazotization-fluoro-de-diazoniation in a liquid-liquid two-phase mixture of pyridine and hydrogen fluoride. Yields for 25 aromatic amines and diamines are 50-100%, except for 2-and 3-fluorobenzoic acid, the three nitroanilines, 3- and 4-diaminobenzene and 4,4 -diaminodiphenyl-oxide (10-50%). In their 1994 paper the authors demonstrate that, in the same system, the photochemical decomposition gives in many cases significantly higher yields than the thermal reaction. The most spectacular increase in yield was found for the fluorination of 2-fluoroaniline where o-difluorobenzene was obtained photochemically in 80.2% yield, but thermally only in 0.6% ...

Selenophene-2-aldehyde takes part in the Hantzsch synthesis [Eq. (I)]108 and reacts readily with ammonia, aromatic amines and diamines,109 hippuric, barbituric, and malonic acids, malononitrile,70 and rhodanine.109 /3-(Selenien-2-yl)acrylic acid has been obtained from selenophene-2-aldehyde by the Perkin reaction and by Knoevenagel condensation with malonic acid.70 Esters of /9-(selenien-2-yl)acrylic acid are easily formed by condensation of the aldehyde... 

Such aromatic amines and diamines, as diphenylamine, iV-methyl-diphenylamine, triphenylamine, benzidine, p-phenylenediamine, etc., are known to have low ionization potentials (75) and to yield univalent positive molecular ions (semiquinones) under ultraviolet irradiation in rigid media (76), or by oxidation in solutions (77). These molecular ions possess characteristic absorption bands in the visible range. 

Nitroxides and benzoquinonediimines are formed from aromatic amines and diamines respectively as a consequence of amine involvement in antioxidant and/or antiozonant processes. Their participation in antioxidant regenerative mechanisms is suggested. Features of phenylenediamine involvement in antiozonant processes are discussed in relation to contemporary theories. 

Of the aromatic amines and diamines, pyridine, 1,10-phenanthroline and neocuproine form moderate active systems with Ru3(CO)i2. Exudation of turnover frequencies in Table 7.7 reveals that a steric effect may instead be operative in the Ru3(CO)i2-amine system, since the rates follow the order pyrrolidine > piperidine, (CH3>2NCH2CH20H > (C2H5>2NCH2CH20H and pyridine > quinoline.

Oxidation bases. These are mostly aromatic amines and diamines which are applied to the fibre (cellulosic or protein) followed by the use of an oxidizing agent.
