Abstract:
Alkene oxidations with various oxidants (tert-butyl hydroperoxide, iodosylbenzene and molecular oxygen in the presence ofisobutyraldehyde (IBA)) catalyzed by transition metal monosubstituted heteropolyanions, PWHMO~ (PWn M; M = Co n, Mn n, Cu n, Ti N, Ru Iv, V v and NbV), have been studied. Orders of catalytic activity of PWHM are different for the oxidants studied. Radical chain mechanisms are proposed for t-BuOOH and O2/IBA. Preliminary coordination oftbe oxidant to PWHM is not a necessary step of its hemolytic activation. Epoxidation with PhIO requires its coordination to the catalyst and most likely includes the formation of active metal-oxo species.
