Owing to the success of Au/CeO2 for catalyzing the oxidation–
cyclization of 1,2-diamines with 1,2-diols, and taking into account
the gold ability for the chemoselective reduction of nitro to amino
groups [54,69–71], we have attempted a one-pot three-step pro-
cess which involves the reaction between 1,2-dinitrobenzene 15
and 1,2-propanediol 2a to achieve the one-pot synthesis of
2-methylquinoxaline as shown in Scheme 7. Firstly, the reduction
of nitro to amino is performed at 10 bars of H2 and 80 °C of temper-
ature. After that, the system is depressurized and flashed out with
N2, and the reaction is continued at 140 °C and atmospheric pres-
sure in the presence of air. The results obtained (see Scheme 7)
indicate that the reduction step is almost quantitative, with com-
plete conversion and selectivity to 1,2-phenylenediamine higher
than 95%. The following oxidation–cyclization step was performed
with excellent results (98% conversion and 85% yield to 3a). There-
fore, Au/CeO2 is a good bifunctional catalyst able to perform the
one-pot three-step reaction between 1,2-dinitrobenzene and
vicinal diols derivatives to give the respective quinoxaline.
4. Conclusions
Au/HT and Au/CeO2 are excellent catalysts for the synthesis of
quinoxaline derivatives of 1,2-propanediol followed by cyclocon-
densation with 1,2-phenylenediamine under base-free conditions,
at mild temperature and using air at atmospheric pressure as oxi-
dant. The reaction network has been established being the diol 2

controlling step) and subsequently to the dicarbonyl compound
5. Both compounds condensate with 1,2-phenylenediamine giving
the quinoxaline 3. The oxidative cleavage of the diol is a competi-
tive reaction which is enhanced by higher temperatures and pres-
sures of the oxidant (air or oxygen). Au/CeO2 can be easily
recovered and reused with a small loss of activity that can be par-
tially restored by removing the adsorbed organic material by a cal-
cination treatment. This calcination treatment should be optimized
to avoid or decrease metal sintering. The regenerated catalyst
maintains high selectivity toward 2-methylquinoxaline. With
Au/HT, it is more difficult to recover the initial activity after some
uses.
The catalytic process presented here has been extended to dif-
ferent substrates (diols and 1,2-diamines derivatives), achieving
good yields of the corresponding quinoxalines. Finally, Au/CeO2 al-
lows to carry out the one-pot three-step synthesis of 2-methylqui-
noxaline starting from 1,2-dinitrobenzene with an excellent global
yield of 83%.
