Ruthenium complexes of N/O/S based multidentate ligands: Structural diversities and catalysis perspectives

Hydration of Nitriles Catalyzed by Ruthenium Complexes: Role of Dihydrogen Bonding Interactions in Promoting Base-Free Catalysis

“…All geometrical parameters including bond distances, bond angles, and torsional angles were in close match to that of similar ruthenium complexes of amide-based NNP ligands . The Ru–N amidate bond distances were marginally shorter than Ru–N heterocycle distances. , On the other hand, Ru–P Ligand bond distances were slightly shorter than Ru–PPh 3 bond distances …”

“…48 The Ru−N amidate bond distances were marginally shorter than Ru−N heterocycle distances. 50,54 On the other hand, Ru−P Ligand bond distances were slightly shorter than Ru−PPh 3 bond distances. 55 Hydration of Nitriles.…”

Carboxamide carbonyl-ruthenium(ii) complexes: detailed structural and mechanistic studies in the transfer hydrogenation of ketones

“…5,6 As a result, many transition metal complexes supported on various ligands bearing well-defined donor atoms have been tailored to achieve the desired catalytic properties. N-Heterocyclic carbenes (NHC), 7 imino-based, amino-phosphines, 8 iminophosphines, 9 carboxamides, 10,11 thiosemicarbazone, 12 aminoalcohols, 13 phosphoramidites, 14,15 selenium-based ligands 16 among others 17,18 are among the common ligands, which have been utilised in the past few years.…”

Cobalt Complexes as Efficient Cooperative Catalysts for Transfer Hydrogenation

“…[8,9] Such drawbacks can be circumvented by utilizing the environmentally benign processes such as transfer hydrogenation (TH) in the presence of a suitable hydrogen source. [10][11][12] TH has received significant attention in the recent years since it is an excellent substitute to hydrogen gas and other hazardous reagents. [13][14][15][16] The saturated alcohols, obtained as the TH products, have widespread applications in the chemical, pharmaceutical and agrochemical industries.…”

“…Both these direct hydrogenation methods present several limitations and drawbacks, such as high‐pressure reaction conditions and highly flammable gas for the former; and significant moisture sensitivity and waste generation for the latter [8,9] . Such drawbacks can be circumvented by utilizing the environmentally benign processes such as transfer hydrogenation (TH) in the presence of a suitable hydrogen source [10–12] . TH has received significant attention in the recent years since it is an excellent substitute to hydrogen gas and other hazardous reagents [13–16] .…”
