UV Laser Photochemistry: Triplet Biradical Trapping Efficiencies and Lifetimes

The trapping of triplet 1,3-cyclopentadiyl (1a) and the triplet 1,4-biradical 2-cyclopent-2-enyl (6) with molecular oxygen has been studied quantitatively.The lifetime of 1a has been found to range between 720 and 900 ns and that of 6 between 53 and 94 ns depending on the solvent.The biradical 1a was found to be trapped in essentially quantitative yield with no indication of oxygen-catalyzed intersystem crossing.In contrast, 6 was found to be trapped in 54-79percent yield with the residual biradical quenching being due to oxygen-catalyzed intersystem crossing.These and other biradical trapping data have been correlated with 1,3-biradical geometries and found to be in accord with Salem's rules for spin-orbit coupling in triplet biradicals.

PREPARATIVE UV-LASER PHOTOCHEMISTRY OF THE AZOALKANE SPIRO(2,3-DIAZABICYCLOHEPT-2-ENE-7',1-CYCLOPROPANE): TRAPPING OF THE 1,4-DIRADICAL 2-(3-CYCLOPENTENYL)ETHYL BY MOLECULAR OXYGEN

Photo-extrusion of nitrogen from the azoalkane 1 in the presence of molecular oxygen gave besides the hydrocarbons 3 and 5, the endoperoxide 10 and hydroperoxide 11, the former via trapping of the 1,4-diradical 4 by triplet oxygen, the latter by ene-reaction of hydrocarbon 5 with singlet oxygen.
