Abstract: The reaction between thiiranes and singlet oxygen has been investigated. Diphenylthiirane is unreactive, but simple alkyl thiiranes react readily, even at low temperature. The products depend on solvent and substrate concentration. In nonnucleophilic solvents, the primary product is the thiirane oxide. In methanol, the primary products are sulfinic esters at low substrate concentration and thiirane oxide at high ...
