Conclusions
In conclusion, the palladium-modied functionalized cyclodex-
trin catalytic system DACH-Pd-b-CD can efficiently promoted the
reduction of nitroarenes in water at room temperature in the
presence of NaBH4. The yields of the desired products are
excellent. What's more, the catalyst can be easily separated from
the reaction media and still maintain high catalytic activity aer
ve cycles. Furthermore, the Pd did not leach out in the solution
during reaction. TEM analyses showed that the average diameter
of the particles was 6 Æ 0.5 nm. All the results indicate that
DACH-Pd-b-CD/NaBH4 is found to be an environmentally-
friendly, efficient and recyclable catalytic system for the reduc-
tion of nitroarenes.
