“…Figure retrieves the construction principle of the above‐mentioned diphosphane DIOP ( 2 , Figure ) in many newer diphosphanes from asymmetric catalysis studies: This is based on recognizing these compounds 5 , 6 , 7 , 8 , 9 , 10 11 , 12 , 13 , 14 , 15 , and 16 consistently as “2,3‐disubstituted‐1,4‐di‐unsubstituted‐1,4‐diphosphanes”.…”

Hexahydropyridazines with CH PAr groups at both N atoms are newly designed 1,4-diphosphanes and were synthesized for the first time. Their N atoms assume a single configuration under the influence of stereocenters at C-5 and C-6. In the solid state, these N-atoms bind the CH PAr substituents axially. Combined with Pd , N,N'-chiral diphosphanes of this kind catalyzed Tsuji-Trost type allylations of dialkyl malonates with racemic 1,3-diphenylallyl acetate efficiently and with up to 91 % ee.

“…Both results are superior to those obtained with a related ligand, bearing PPh 2 groups (iso/n-ratio = 57/43, 25 %ee) instead of the BNP-unit. DIOPtype BNP-ligands were used furthermore in the Rh-catalyzed asymmetric hydrogenation of standard substrates (14-34 %ee) and in the Rh-catalyzed hydroformylation (17-34 %ee) [43].…”

“…14 Groups providing solubility of structural analogues of (7)-DIOP in water can be present not only in the aromatic fragments of the ligand (for example, quaternised compound 9e) but also in the dioxolane ring. For example, among compounds 15a ± e, which were prepared from condensation products of diol 16 with various aldehydes or ketones, 9,15,16…”

Methods for the synthesis of chiral organophosphorus Methods for the synthesis of chiral organophosphorus compounds based on natural optically active compounds compounds based on natural optically active compounds (hydroxy acids, amino acids and their derivatives, mono-and (hydroxy acids, amino acids and their derivatives, mono-and disaccharides, mono-and diterpenoids, steroids) are discussed. disaccharides, mono-and diterpenoids, steroids) are discussed. Particular attention is given to the synthesis of bisphosphines and Particular attention is given to the synthesis of bisphosphines and bisphosphinites. These compounds serve as ligands for transition bisphosphinites. These compounds serve as ligands for transition metal complexes, which catalyse asymmetric hydrogenation.
