2,4,6-Triphenyl-<I>s</I>-triazine (II) is formed either in the chemiluminescence reaction of 2,4,5-triphenylimidazole (I) in the presence of oxygen and a strong base or in the photolysis of I in alcohol in the presence of ammonia and oxygen. II is also formed in the sensitized photo-oxygenation of I in alcohol containing ammonia. It was found that II was produced by the reaction between the lophyl hydroperoxide (V), which was prepared from I and was known to be one of the intermediates in chemiluminescence reaction of I, and ammonia. Chemical and spectroscopic evidence that II is produced from V and not <I>via</I> the dioxetane-type peroxide (VI) nor <I>N</I>,<I>N</I>′-dibenzoylbenzamidine (IV), is given. II and several other 2,4,6-triaryl-<I>s</I>-triazines were found to be easily prepared from the corresponding triarylimidazoles by the sensitized photo-oxygenation in methanol in the presence of ammonium acetate and this provides a new method for the synthesis of triaryl-<I>s</I>-triazine.
