Singlet Molecular Oxygen

Reactions of singlet oxygen are of much current interest because of their importance in photooxidations of chemical and biological systems, including reactions used in photo-chemotherapy. Rate constants for the chemical reaction and physical deactivation of singlet oxygen have been critically compiled from the literature through 1993. Solvent deactivation rates are tabulated for 145 solvents and second-order rate constants for 1,915 compounds with singlet oxygen are reported. This publication supersedes Wilkinson and Brummer, J. Phys. Chem. Reference Data 10: 809 (1981).

Sixteen tables give rate constants or beta values with solvent, method, and other details for reactions of singlet oxygen with:

• olefins
• aromatics
• phenols and naphthols
• furans, pyrans and other heterocyclic oxygen compounds
• pyrroles, oxazoles, pyridines and other heterocyclic nitrogen compounds
• porphyrins, phthalocyanines and polypyrroles
• aliphatic and alicyclic amines
• aromatic amines
• amino acids, peptides and proteins
• diazo compounds and dyes
• metal complexes
• sulfur, selenium and tellurium compounds
• inorganic compounds
• oximes, hydrazones, nitrones, nitroso compounds and N-oxides
• some compounds of biological interest
• miscellaneous substrates
