Highly efficient chiral PNNP ligand for asymmetric transfer hydrogenation of aromatic ketones in water

Asymmetric hydrosilylation, transfer hydrogenation and hydrogenation of ketones catalyzed by iridium complexes

“…This catalytic system is also efficient in the asymmetric transfer hydrogenation of aromatic ketones with HCOONa in water, giving the corresponding optically active alcohols again in high yields and excellent e.e. (up to 99%) [57]. In the presence of a different metal precursor, [IrH(CO)(PPh 3 ) 3 ], ligand 62 afforded a 90% e.e.…”

Half-sandwich iridium complexes—Synthesis and applications in catalysis

“…Half-sandwich iridium chloro, aminocarboxylate, amino alcohol, and diamine complexes are excellent catalysts for a range of hydrogen transfer reactions, including asymmetric transfer hydrogenation (ATH) in organic media or in water [5,69,70,[87][88][89][90][91][92][93]. Described below are selected recent examples of alcohol oxidation, ATH of ketones, and dynamic kinetic resolution of imines and alcohols.…”

Synthesis and characterizations of N,N,N′,N′-tetrakis (diphenylphosphino)ethylendiamine derivatives: Use of palladium(II) complex as pre-catalyst in Suzuki coupling and Heck reactions

“…The improved catalytic activity of transition metal complexes with hemilabile ligands has been extensively reviewed [11][12][13][14]. There has been recently increasing interest in the synthesis of highly active transition metal based catalysts derived from aminophosphines that can be used in different catalytic reactions including allylic alkylation [15][16][17][18], ammination [19][20][21], Heck [22][23][24][25][26][27][28][29][30], Suzuki [31][32][33][34][35], hydroformylation [36][37][38][39] and hydrogenation reactions [40][41][42][43][44]. Palladium containing catalysts serve as straightforward and extremely powerful reagents for the carbon-carbon bond formation [45][46][47].…”
