HSO−4 . The importance of the tungsten(VI) source stressed
previously [18,19,22–26,29] is highlighted once again by
the strong activity increase at room temperature when using
WO3·H2O instead of Na2WO4·2H2O.

Moreover, using the WO3·H2O/H2O2–H2O–H3O+/[CH3-
(n-C8H17)3N]+H2PO4−/toluene catalysis system, the prepara-
tion of not-too-sensitive epoxides can be carried out with good
selectivity at room temperature. For acid-sensitive epoxides,
comparing the effects of such buffers as CO2·H2O/HCO−3 or
H2PO−4 /HPO24− showed that the latter appears to be superior
in terms of conversion and selectivity, due in part to the phos-
phate ion’s ability to act as an assembling ligand, in contrast
to the carbonate anion. It was demonstrated that the WO3·H2O
/H2O2–H2O–H3O+/[CH3(n-C8H17)3N]+H2PO−4 /cyclooctene/
toluene catalysis system can be reused in 5 consecutive runs
with no loss in activity. To reach long lifetimes of the oxoper-
oxo-metal systems, these tungsten-based systems, active at 20–
40 ◦C, can compete in terms of yields and selectivities for the
synthesis of very sensitive epoxides with the CH3ReO3/H2O2–
H2O/Brönsted bases/organic solvent two-phase reagents [47,
50]. Thus, with (R)-(+)-limonene, the primary oxidation prod-
ucts are limonene-1,2-epoxides, with a very high regioselec-
tivity, because formation of limonene-8,9-epoxides is not ob-
served. Moreover, the highly selective formation of a 1:1 mix-
ture of trans/cis-1,2-epoxides is obtained with tungsten(VI)- or
rhenium(VII)-based systems (this work and [47]). The former
are quite complex and interesting from equilibrium and dy-
namic standpoints; further kinetic studies are needed to explore
the detailed mechanisms in these systems. The active species
must have an appropriate partition coefficient, one that allows
it to interact with both the organic medium and the aqueous
oxidant for regeneration. We now have a reliable approach to
choosing the ideal alkyl ammonium salt that avoids the need
for trial-and-error experiments. Further applications of this cat-
alytic system to other oxidations are under investigation.
