CHEMISTRY OF SINGLET OXYGEN - 38. TEMPERATURE EFFECT ON THE PHOTOOXIDATION OF SULFIDES.
Gu,Foote
, p. 6060 - 6063 (1982)
The reactivity of diethyl sulfide with singlet oxygen has been determined at room temperature (23-24 degree C) and at minus 78 degree C in various solvents. Although the consumption of sulfide is much faster at minus 78 degree C, the rate of removal of singlet oxygen by sulfide is relatively independent of solvent and temperature. A comparison of the rate of product formation with the rate of singlet oxygen removal shows that over 97% quenching is observed in aprotic and about 10% in protic solvents at room temperature. At minus 78 degree C, the quenching process is suppressed in both protic and aprotic solvents. Surprisingly, 2,5-diphenylfuran showed a similar but much smaller effect of solvent and temperature.
Effect of alcohols on the photooxidative behavior of diethyl sulfide
Clennan, Edward L.,Greer, Alexander
, p. 4793 - 4797 (1996)
The reactions of singlet oxygen with diethyl sulfide (Et2S) in benzene alcohol mixtures have been examined. The salient discoveries include: (1) the rate constants of product formation, kr, in benzene/methanol mixtures are a function of the concentration of methanol, (2) the ability of alcohols to supress physical quenching are a function of their pKa's, and (3) trapping experiments with diphenyl sulfoxide are consistent with two distinct intermediates. A mechanism which involves formation of a persulfoxide followed by reaction with methanol to give a hydroperoxy-methoxy sulfurane is consistent with all of the results.

A novel Ti-W-O-cluster-substituted tungstoantimonate (TA), [H2N(CH3)2]3Na4H9[{Ti6W4O18(OH)(H2O)3}(B-α-SbW9O33)3]·20H2O (1), has been made by hydrothermal reactions of trivacant [B-α-SbW9O33]9- units, Ti4+ cations, and WO42- anions in the presence of [H2N(CH3)2]·Cl and structurally characterized. Intriguingly, the polyoxoanion of 1 is constructed from three [B-α-SbW9O33]9- units and a previously unobserved decanuclear heterometallic Ti-W-O cluster [Ti6W4O18(OH)(H2O)3]11+ ({Ti6W4}) that is comprised of an octahedral [Ti6WO6(H2O)3]18+ cluster and an edge-sharing [W3O12(OH)]7- fragment via six W-O-Ti/W linkers. Furthermore, studies on the catalytic oxidation properties reveal that 1 possesses good catalytic activity toward the oxidation reactions of various sulfides and cyclooctene based on the environmentally friendly oxidant H2O2.

Herein, we demonstrate the highly efficient photocatalytic sulfide oxidation reaction under mild conditions,i.e.in air, at room temperature and in the absence of a sacrificial reagent, co-catalyst or redox mediator, by using ultrathin C,N-TiO2nanosheets as a photocatalyst.
