O. Tissot et al., X-RAY CHARACTERIZATION OF ENANTIOMERICALLY PURE 1'-DIPHENYL-3,3',4,4'-TETRAMETHYL-2,2'-BIPHOSPHOLE - A LIGAND WITH AXIAL AND CENTRAL CHIRALITY, Chemical communications, (19), 1996, pp. 2287-2288
The stereochemical analysis and characterization of diastereoisomers o
f 1,1'-diphenyl-3,3',4,4-tetramethyl-2,2-biphosphole having axial and
central chirality reveal the potential interest of this ligand for asy
mmetric catalysis.
