    Photolysis of Olefin IMI and Its Photolytic Products

      Graphical Abstract
      • Abstract
    • A study was done on photic stability,photolytic dynamics and pathway of photolytic metabolism of olefin IMI.Results show that olefin IMI was stable in darkness.It decreased by 3% in concentration after having been kept in room temperature and darkness for 400 days.However in the laboratory under simulated sunlight,olefin IMI was unstable and easily degraded.Its photolytic reaction fitted the first-order kinetic equation(r>0.99),and its half life was figured out to be 4 days.Its photolytic reaction followed two pathways,either through hydroxylation into 4,5-dihydroxy IMI,which is oxidized,breaking its nitroimine pharmacophore and turned into carbonyl product,or through formation of guanidine metabolites by breaking off nitroimine group.
