- Selective oxidation of DDT by dioxygen on the dioxo-Mo(VI) complex anchored on a TiO2 under UV-irradiation
-
Oxidation of DDT (1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane) by the dioxo-Mo(VI) complex (dioxo-molybdenum(VI)-dichloro[4,4′-dicarboxylato-2,2′-bipyridine]), anchored on a TiO2, in the presence of dioxygen under UV-irradiation (λ = 253.7 nm) in acetonitrile suspension has been examined. The reaction has catalytic character. Conversion of DDT (35% for 32 h reaction) to dicofol (2,2,2-trichloro-1,1-bis(4-chlorophenyl)ethanol, 21%) and a great number of other chlorinated and non-chlorinated products of the oxidative/reductive decomposition proceeds by the primary reaction of oxo-atom transfer from dioxo-Mo(VI) complex to bibenzylic-carbon atom of DDT. The catalytic cycle is performed via the re-oxidation of the reduced Mo(IV) into Mo(VI) by dioxygen in the "dark" reaction.
