Modular P‐Chirogenic Aminophosphane‐Phosphinite Ligands for Rh‐Catalyzed Asymmetric Hydrogenation: A New Model for Prediction of Enantioselectivity

“…[2,3,6] To improve an asymmetric catalytic reaction for a new substrate is not trivial, however, possible approaches being mainly restricted either by the availability of a library of chiral ligands, [3,6] or to the easy structure modification of an efficient lead series such as BINAP, [16,17] DUPHOS, [18] PHOX, [19] monophos, [20] etc. In particular, the phosphorus and phosphinous derivatives usually prepared by treatment of PCl 3 or chlorophosphanes with available chiral diols, [21,22] binaphthol, [23][24][25] or amino alcohols [26][27][28][29][30][31] offer an efficient and easy route to new chiral ligands. Notably, the phosphorus ligands are by far the most commonly used ones, [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] because they offer far more possibilities for modification of the structure (mono-, di-, multidendate, hemilabile, hybrids, etc.…”

Application of N,N‐bis(diphenylphosphino)aniline palladium(II) complexes as pre‐catalysts in Heck coupling reactions

“…The ligands (1)(2)(3)(4)(5) 53,54 and the palladium complexes (1a-5a) 55 -59 were prepared according to literature procedures. Heck coupling reactions were conducted as follows: aminophosphine-palladium complexes (1a-5a; 1.0 mmol%), aryl bromide (1.0 mmol), styrene (1.5 mmol), K 2 CO 3 (2 mmol) and dioxane (3 ml) were placed in a Schlenk tube and the mixture was heated to 80…”

New bis(diphenylphosphino)aniline derivatives: Synthesis and spectroscopic characterization

“…The reaction condition for the synthesis of aminophosphines depends on the nature of chlorophosphine and the organic precursor. For the obvious electronic reasons, Ph 2 PCl is more reactive toward a nucleophile than chlorodialkylphosphines [3]. Over the past years, studies of aminophos- phines have attracted a considerable attention because aminophosphines consist of both soft and hard donor atoms to accommodate metal ions.…”
