Multifactorial analysis in the study of hydroformylation of oct-1-ene using supported aqueous phase catalysis

Mono and dinuclear complexes of half-sandwich platinum group metals (Ru, Rh and Ir) bearing a flexible pyridyl-thiazole multidentate donor ligand

“…Despite the diversity of these potential applications, relatively little is known about how the properties of electron transfer between a single donor and acceptor is influenced by their inclusion into larger supramolecular assemblies. In this regard, ruthenium complexes bridged by multiple nitrogen donor polypyridyl ligands have received considerable recent attention because of their possible applications in homogeneous catalysis [16][17][18][19][20][21], as multi electron storage system [22][23][24], in the designing of new materials [25][26][27][28] and in photophysical and photochemical molecular devices [29][30][31][32][33]. One of the simplest linker used in assembling metals in such arrays is 4,4 0 -bis(2-pyridyl-4-thiazole) (L).…”

A comparative study of supported aqueous- and ethylene glycol-phase catalysts in stilbene hydrogenation: Influence of the different modes of dispersion of supported liquids

“…Figure 2 The influence of liquid loading was examined by other research groups for hydroformylation [3,[11][12][13][14][15], hydrogenation [7,8], Heck coupling [22] and alkylation [29]. For example, Delamas and co-researchers indicated that a maximum activity of Rh-SLPC-W for hydroformylation occurred before the pore volume of the support material was fully filled with water [14]. However, those previous experiments were carried out at the conditions where the total amount of the metal complexes was kept constant; that is, the concentration of the metal complexes in the supported liquid was changed.…”

“…This is significant because overall reaction rates in biphasic systems are sometimes limited by low liquid-liquid interfacial areas and it is difficult to increase this area by mechanical agitation [9]. The concept of SLPC is well proven in the cases of hydroformylation [2][3][4][5][10][11][12][13][14][15][16], hydrogenation [6][7][8][17][18][19][20], Heck reactions [21][22][23][24][25][26][27][28] and alkylation [29]. Recently, it has also been reported that simultaneous use of two types of SLPC samples can give bi-functional catalyst systems, which are sometimes difficult to obtain by the use of mixtures of homogeneous or biphasic metal complex catalysts because of undesired negative interactions between the different metal complexes [19].…”

Spectral, structural and DFT studies of platinum group metal 3,6-bis(2-pyridyl)-4-phenylpyridazine complexes and their ligand bonding modes

“…Polypyridyl complexes of platinum group metals are being continuously investigated because of their multiple applications in fields of science including photophysics and photochemistry [1][2][3][4][5][6], supramolecular chemistry [7], catalysis [8][9][10][11][12][13] and bioinorganic chemistry [14][15][16][17][18][19]. The organometallic complexes of g 6 -arene ruthenium [20,21] and g 5 -half-sandwich complexes of rhodium and iridium have attracted considerable current interest as potential anticancer agents (Dyson et al) [14][15][16][17][18][19]22,23].…”
