Transfer hydrogenation of nitroarenes using cellulose filter paper-supported Pd/C by filtration as well as sealed methods

Abstract

A novel and efficient catalytic filtration has been developed for the selective reduction of nitro compounds on a Pd/C-doped cellulose filter paper.

Catalytic filtration: efficient C-C cross-coupling using Pd(II)-salen complex-embedded cellulose filter paper as a portable catalyst

“…Based on the results, the plain FP has a pore size and a specific surface area of 8.66 microns and 1.52 m 2 g −1 respectively, which reaches to 6.46 microns and 1.66 m 2 g −1 after silylation. 19 The specific surface area increased to 3.55 m 2 g −1 after surface modification of the silylated FP with Pd-salen complex. Also, the average pore size was decreased to 1.60 microns upon this modification.…”

“…EDX and ICP analyses confirmed the successful functionalization of the plain cellulose filter paper, wherein % wt Si was found to be 14.68, and 11.36 respectively. 19 This amount provides suitable substrate for the next functionalization on the silylated sites.…”

“…The results showed a correlation between these two parameters that with the suitable surface functionalization, both improve. 19 …”

“…After the reaction completion, the recovered FP pieces were shaken in absolute EtOH (15 mL) to achieve the highest efficiency, and the resulting solution was added to the final mixture to calculate the reaction efficiency. 19 …”

“…The application of this system was recently demonstrated by the transfer hydrogenation of nitroarenes using cellulose filter paper-supported Pd/C by filtration methods. 19 …”
