Oxidation-State-Dependent Photochemistry of Sulfur-Bridged Anthracenes

摘要

In chemical synthesis, functional group tolerance often determines the utility of a reaction. Where one functional group may inhibit reactivity, another may accelerate the rate ten-fold. In photochemical reactions, slight modifications in functional groups can also have dramatic consequences, with electronic and conformational configurations determining how molecules behave in the presence of light. In order to better predict the outcomes and rationally design photochemical syntheses, a broader understanding of functional group behavior is needed. Organic sulfides, sulfoxides, and sulfones are common functional groups relevant to pharmaceutical, agrochemical, and light-emitting compounds. The photochemistry of various alkyl and aryl sulfoxides has been examined by Lee and Jenks with a focus on the mechanism of pyramidal inversion at sulfur.
