Synthesis of Pd immobilized on functionalized hexagonal mesoporous silica (HMS–CPTMS–Cy–Pd) for coupling Suzuki–Miyaura and Stille reactions

Synthesis and characterization of thiophene-derived palladium(ii) complex immobilized on FSM-16 and its application in the novel synthesis of 7-(aryl)-7,12-dihydro-6H-indeno[1,2,4]triazolo[1,5-a]pyrimidine-6-one derivatives

“…[10][11][12][13][14][15][16][17] Also, some important works reported on the synthesis of mesoporous Pd based nanocatalyst are Fe 3 O 4 @SiO 2 @IL-PMO/Pd, Fe 3 O 4 @MePMO-IL/ Pd, HMS-CPTMS-Cy-Pd, MCM(Pd)-41. [18][19][20][21] In this regard, FSM-16 has attracted great attention, as compared with other porous materials. Accordingly, a folded-sheet mechanism is applied, which results in forming a hexagonal array of channels.…”

Pd-Catalyzed Cross-Couplings: On the Importance of the Catalyst Quantity Descriptors, mol % and ppm

“…Its wider application enabled easier data extraction in this study. We identified 75 journal articles, which included a total of 97 individual reactions, from which good quality data could be extracted and analyzed. ,,,,− The data shows a split between common mol % choices, 0–1 and 4–5 mol %, having ppm values up to 1000 ppm. It also shows that, from these selected papers, lower mol % values are preferred with ca.…”

“…We analyzed 42 journal articles and 61 separate Pd-catalyzed reactions (Figure ). ,,,,− ,,,,,− There is a preference for lower mol % ranges, but more reactions are performed at 5 mol %, which is particularly apparent in older articles. There is a larger variation in ppm values for the 4–5 mol % category, most likely due to the large variation in reaction volume.…”
