“…The first use of in cellulo palladium chemistry in mammalian cells was reported by Yusop [15 ], who trapped palladium nanoparticles within inert polymeric microspheres, with the catalysts evolving from recyclable and ligand free heterogeneous palladium catalysts [32]. It also built upon work which demonstrated the routine Palladium mediated chemistry in living cells Chankeshwara, Indrigo and Bradley 131 Ref.…”

“…In these reports the highly active heterogeneous catalytic system developed by Yusop [15 ] and Cho [32] converted the caged 5-fluorouracyl (5FU) [16] and Gemcitabine [17] analogues to their active forms in culture with colorectal HCT116 and pancreatic BxPC-3 cancer cell lines. 5-Propargyl fluorouracyl (Pro-FU) released the 5-FU within 24 h, producing an effect comparable to 5-FU antiproliferative activity.…”

The effects of the ligand used for fabricating palladium (Pd)-incorporated porous polymer composites on their catalytic performances were examined from the perspective of catalysis sustainability. To perform this research, poly(amidoamine) (PAMAM) dendrimers, which were generation zero (G0) and higher, up to G6, the breakdown structure of G0 (that is, the half (G0h) and quarter (G0q)) and a typical small molecule (that is, N,N-dimethyl ethylenediamine (DMEn)) were utilized as ligands. The catalytic performances of the polymer composites were investigated using the aqueous Suzuki-Miyaura carbon crosscoupling reaction as a model reaction. Concerning the efficiency, recyclability and Pd-leaching behavior of the catalytic reaction, polymer composites that were fabricated with PAMAM dendrimers (that is, G1 and higher generations) proved to possess the potential for application as sustainable heterogeneous catalysts.

“…The resulted resin was then filtered and washed with DCM (5 x 20 mL), methanol (5 x 20 mL), DMF (5 x 20 mL) to remove any impurities from Pd/FTO catalyst. 30 Afterwards, Pd/FTO was dried to get the final Pd/FTO catalysts.…”

Immobilization of palladium nanoparticles onto the fluorine-doped tin oxide (FTO) as support Pd/FTO, resulted in a highly active heterogeneous catalyst for Suzuki-Miyaura cross-coupling reactions and 4-nitrophenol reduction. The Pd/FTO catalyst has been synthesized by immobilization of palladium nanoparticles onto FTO via a simple impregnation method. ICP-MS analysis confirmed that there is 0.11 mmol/g of palladium was loaded successfully on FTO support. The crystallinity, morphologies, compositions and surface properties of Pd/FTO were fully characterized by various techniques. It was further examined for its catalytic activity and robustness in Suzuki coupling reaction with different aryl halides and solvents. The yields obtained from Suzuki coupling reactions were basically over 80%. The prepared catalyst was also tested on mild reaction such as reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). Pd/FTO catalyst exhibited high catalytic activity towards 4-NP reduction with a rate constant of 1.776 min-1 and turnover frequency (TOF) value of 29.1 hr-1. The findings revealed that Pd/FTO also maintained its high stability for five consecutive runs in Suzuki reactions and 4-NP reductions. The catalyst showed excellent catalytic activities by using a small amount of Pd/FTO for the Suzuki coupling reaction and 4-NP reduction.
