摘要：

The chemistry of singlet molecular oxygen, generated by the reaction of hydrogen peroxide with metal hypochlorites, has been studied. In all cases, the chemistry is identical with that of the reactive intermediate in the dye-photosensitized oxygenation of olefins and dienes. The techniques used for comparison of the two reactions include detailed studies of stereoselectivity with a variety of acceptors, determination of the ratio of the rates of reaction and decay for the intermediate, relative reactivities of acceptors, and substituent effects on product and reaction rate. From the results of these studies, it is concluded that the reactive intermediate in both the photosensitized and chemical oxygenation is O2 (Δg). The reaction with olefins appears to be a concerted cycloaddition, and there is little polar or diradical character developed at the transition state. © 1968, American Chemical Society.
