Then the prepared Pd-DAC-Sch system was evaluated as a heterogeneous nanocatalyst for aryl halide cyanation in the presence of K4[Fe(CN)6] and for reduction of nitroarenes to amines using NaBH4 in water at room temperature. Pd-DAC-Sch nanocatalyst efficiently cyanated various aryl halides by providing satisfactory reaction yields of 87–98%. Moreover, Pd-DAC-Sch catalyzed 4-nitrophenole (4-NA), 2-nitroaniline (2-NA), and 4-nitroaniline (4-NA) reductions in short reaction time. More importantly, Pd-DAC-Sch nanocatalyst was reapplied up to six successive runs by giving a yield of 86% without any important changes in its morphology and structure. This paper shows that Pd-DAC-Sch is a highly effective, reusable, chemically stable, and therefore a useful nanocatalyst.eninfo:eu-repo/semantics/embargoedAccessBenzonitrilesDialdehyde CelluloseNanoparticleNitroareneArticle2984475449310.1007/s10570-022-04550-5Q1WOS:000779983400002Q1
