✦ Synopsis

We have found that substituent groups and solvents may have striking effects on the rates of bimolecular reactions involving nucleophiles and photoexcited nitroaromatic compounds. As representative cases, data on reactions of cyanide ion and 4-nitroanisole, l-nitronaphtbalene. and 4-methoxy-1-nitronaphthalene are reported in this communication.

Preparative reactions were carried out with solutions 10-S M in nitroaromatic and IO-2 M in cyanide irradiated with a 450 w Hanovia immersion lamp equipped with aPyrex filter. For quantum yield measurements an Osram 200 w super high pressure lamp was used and a narrow band was selected by a Bausch and Lomb high intensity monochromator.

## Abstract The reactions of stabilized carbonium ions of setoglaucin, methyl violet, and ethyl violet with cyanide ions are largely catalyzed by the cationic micelles of cetyltrimethylammonium bromide (CTAB) in aqueous media. Added counterions (anions in this case) have strong inhibitory effects o
