Then the ask was naturally cooled down for around 2 min,
followed by the addition of 0.1 mmol of anisole as the internal
standard. The catalyst was ltered out and the aromatic
compounds were extracted from the reaction solution using
toluene for three times (the volume usage of toluene and the
reaction solution is 6 : 1), and the organic phase was analyzed
by gas chromatography (GC). The reactions performed under
other conditions were achieved with the same procedure except
that the relevant parameters were adjusted as required. The
radicals generated during the oxidation reaction were probed by
electron paramagnetic resonance (EPR) on a Bruker EMS-plus
instrument. The EPR data were analyzed with Xeon soware
