Abstract:

The reaction of an aminocoumarin carboxylic acid chloride Coumarin 343 with 1-phenethyl hydroperoxide results in light emission that is easily detected with the unaided eye. This reaction proceeds through a secondary perester intermediate. Intramolecular electron exchange, modeled after the analogous process in the bioluminescence of the Firefly, is proposed as the mechanism for light generation. Attempts to carry out this reaction under conditions where the coumarin acid is recycled were not successful.
