| Abstract: | Simple aliphatic aldehydes, when mixed with hydrogen peroxide in acidic, aprotic solvents containing copper I, chemiluminesce weakly. The reaction is very specific for copper I. Quantum yield determinations reveal a catalytic role for copper I and a 1:1 stoichiometry for aldehyde and hydrogen peroxide. Kinetics reveal that an aldehyde/peroxide adduct is the active compound and synthetic l-hydroxy octyl hydroperoxide is completely active in the reaction. Similarities in substrates. kinetics and insensitivity to extraneous substances suggest this reaction as a model for earthworm bioluminescence. |
