10-Methyl acridinium chloride

The weak chemiluminescence from lucigenin in alkaline DMSO solutions in the absence of O2 may involve similar reactions. Cyanide ions also react with lucigenin to give light in the presence of oxygen [7]. Again N-methyl acridone is the emitter and the biacridanyl derivative (6) appears to be an intermediate. An equilibrium between (6) and the radical (7) is proposed. Addition of cyanide ion to N-methyl acridinium chloride in air-saturated DMSO or DMF produces the same radical. 

A very high chemiluminescence quantum yield (about eight times that of luminol) has been reported for the oxidation of N-methyl-9-benzyl acridinium chloride with potassium persulfate as catalyst [17]. Although no mechanism has been determined the reaction is reminiscent of the oxidation of 9-methyl acridine [15] in which the carbanion reacts with oxygen to produce the dioxetan which presumably decomposes in the accepted fashion for such compounds ...
