Photosensitized Electron Transfer from Azoalkanes: Generation, Fragmentation, and Rearrangement of Radical Cations Structurally Related to Dicyclopentadiene

Article abstract of DOI:10.1021/jo00072a008

The azoalkanes 1a-c extrude nitrogen upon photosensitized electron transfer (PET) to yield 1,3-radical cation intermediates 2(.+), which undergo interesting transformations.Electron back transfer (BET) affords the unrearranged housanes 2, but significant
