using an Agilent model 4890D gas chromatograph with a
flame ionization detector and a PEG-20M capillary column
(
50 mꢂ0.32 mmꢂ0.4um). Quantification of components was
based on the internal standard technique using 1,2,4,5-tetra-
methylbenzene. Real-time in situ infrared spectra measure-
ments were carried out on a Mettler toledo ReactIRꢃ 45 m
equipped with an external AgX fiber conduit diamond ATR
probe. H nuclear magnetic resonance ( H NMR) spectra
were recorded on a Bruker DRX-400FT using DMSO-d as
the solvent with TMS as an internal reference. Data are re-
ported as follows: chemical shift in parts per million (d,
ppm), integration, multiplicity (s=singlet, br s=broad sin-
glet, d=doublet, t=triplet, q=quartet, and m=multiplet),
and coupling constants (Hz). C NMR spectra were record-
ed on a Bruker DRX-400FT at ambient temperature. Chem-
ical shifts are reported in ppm from DMSO-d6 taken as

Typical Procedure for the Oxidation

Catalytic reactions were performed in a 70-mL autoclave re-
actor with

a
teflon insert. Typically, toluene (2 mL,
(OAc) ·4H O (1.25 mol%),
18.8 mmol), NHQI (5 mol%) CoACHTGNUTRENNUNG

and acetonitrile (7 mL) were placed in the reactor. After the
autoclave had been sealed, the air inside was replaced with
O for three times. Then the reactor was heated to the reac-
tion temperature, while agitation was ensured by an external
magnetic stirrer. Upon heating to the reaction temperature,
the reactor was charged with 0.5 MPa of O and O was fed
continuously to maintain a constant pressure. After the reac-
tion, the mixture was cooled to room temperature, and ana-
lyzed by gas chromatography.
