The rate constants, k(T), k(r), and k(Q), corresponding to the substrate induced total removal, chemical removal, and physical removal of singlet oxygen, respectively, have been measured for a series of sulfenamides. The structural effects on the partitioning of the persulfinamide intermediate along the chemical and physical deactivation pathways is discussed.
Photooxidation of sulfenic acid derivatives. 4.1,2 Reactions of singlet oxygen with sulfenamides

The reactions of singlet oxygen with nine sulfenamides are reported. A detailed kinetic study reveals that two intermediates are required on the photooxidation reaction surface. One intermediate acts as a nucleophile and the second intermediate as an electrophile in their reactions with diaryl sulfoxides and diaryl sulfides, respectively. Physical quenching is also suppressed in the sulfenamides relative to other sulfur-containing singlet oxygen substrates. The mechanism of the reaction is discussed and compared to diethyl sulfide photooxidation, and a rationale for the decreased importance of physical quenching in these substrates is presented.
