Photomechanistic Aspects of Bicyclic Azoalkanes: Triplet States, Photoreduction, and Double Inversion

This contribution is preceded by an earlier chapter, which covered the main topics of the photochemistry of cyclic azoalkanes for over three decades. Herein, we address the following mechanistic aspects of cyclic azoalkane photochemistry: (1) the generation of azoalkane triplet states on direct irradiation and their photochemical transformations, and (2) the double inversion of the molecular skeleton in the formation of housane during photochemical nitrogen extrusion.
