Functionalized cellulose with multiple binding sites for a palladium complex catalyst: synthesis and catalyst evaluation in Suzuki–Miyaura reactions

Recent Developments in the Immobilization of Palladium Complexes on Renewable Polysaccharides for Suzuki–Miyaura Cross-Coupling of Halobenzenes and Phenylboronic Acids

“…Then it was filtered magnetically and the obtained solid, nano-Fe3O4@AOFC/Pd(II) was washed with water and dried under vacuum. (3) addition of Na 2 PdCl 4 to yield the final catalyst [109]. Both 13 C-NMR and FTIR analyses corroborate that cellulose has successfully been modified for the metal-ligand interaction.…”

“…Moreover, in recycling tests, the Pct-Pd catalyst exhibited superior performance as it continued to produce high yields of 91% even after 12 runs, during which only negligible metal leaching was observed. (3) addition of Na2PdCl4 to yield the final catalyst [109]. Both 13 C-NMR and FTIR analyses corroborate that cellulose has successfully been modified for the metalligand interaction.…”

“…The performance of the catalyst in Suzuki cross-coupling, using chlorobenzene, idobenzene and different bromobenzenes with phenylboronic acid derivatives in EtOH/H 2 O (1:1) at 70 • C, yielded TOFs from 53 to 341 h −1 [109]. The catalyst was also tested for reusability for five runs, during which the yield of 4-methoxybiphenyl decreased from 96% to 77%.…”

“…Adapted from ref [108]. with permission from Elsevier.Dong et al[109] reported on the synthesis of new heterogeneous palladium catalyst in three steps: (1) cellulose was reacted with 3-aminopropyltriethoxysilane to yield Cell-NH 2 ; (2) synthesis of Schiff-base functionalized cellulose;…”

Highly Active Cellulose-Supported Poly(hydroxamic acid)–Cu(II) Complex for Ullmann Etherification

“… 27 − 32 In addition, most researchers have been focusing on exploring a new type of ligand to functionalize the cellulose surface, which has a profound impact on the catalytic ability with low leaching of metal species. 10 …”
