of electron density within the biaryl skeleton but has a very small influence on the torsion angle. The most important consequence of this structural alteration is the dramatic increase in configurational stability of homochiral F8BINOL.
[结构:见正文]在BINOL的5、5',6、6',7、7',8和8'位置,
氟被氢取代强烈影响联芳基骨架中电子密度的分布,但具有非常强的对扭转角的影响很小。这种结构改变的最重要结果是同手性F8BINOL的构型稳定性急剧增加。
