'''BINAP''' 是有机化合物'''2,2'-双二苯膦基-1,1'-联萘'''的缩写。这种[[光学异构体|手性]][[配体]]广泛的应用于[[手性合成|不对称合成]]。它由一对2－二苯基膦[[萘|萘基]]连接1和1'位（图1）所组成。该C2-对称框架不存在[[手性中心|手性原子]]（参见[[轴向手性]]）。由于空间位阻，双萘环的消旋障碍很高从而限制了连接两萘环的化学键自由旋转（参见[[阻转异构体]]）。其萘环平面形成的[[二面角]]约为90˚。

== 应用 ==
在有机化学中，可使用BINAP与[[钌]]、[[铑]]和[[钯]]的[[络合物]]催化剂进行对映选择性反应。<ref>{{cite journal |last=Kitamura |first=Masato |coauthors=M. Tokunaga, T. Ohkuma, and R.

这种合成方法最早由[[高砂香料工業|高砂香料工業株式會社]]工业化。也因为这项工作，[[野依良治]]获得了2001年度的[[诺贝尔化学奖]]。

。R构型，S构型的[[对映体]]或其[[消旋体]]都是商业市售试剂。BINAP与铑共轭的试剂为一种广泛使用的化学选择性氢化催化剂。
