Substitution of hydrogens by fluorines at the 5, 5', 6, 6', 7, 7', 8, and 8
' positions of BINOL strongly affects distribution of electron density with
in the biaryl skeleton but has a very small influence on the torsion angle,
The most important consequence of this structural alteration is the dramat
ic increase in configurational stability of homochiral F8BINOL.
