'''SEGPHOS'''是一种用于[[不对称合成]]的[[手性]][[配体]]。<ref>{{cite journal | author = Shimizu, H., Nagasaki, I., Matsumura, K., Sayo, N., Saito, T. | title = Developments in Asymmetric Hydrogenation from an Industrial Perspective | year = 2007 | journal = [[Acc. Chem. Res.]] | volume = 40 | issue = 12| pages = 1385–1393 | doi = 10.1021/ar700101x | pmid = 17685581 }}</ref> <br />
<br />
它是继[[BINAP]]之后被发现的配体。SEGPHOS被测量出其芳香环之间具有较狭窄的二面角。因此SEGPHOS被预测能增加金属络合物的对映选择性与活性，以上推测后经实验被证实。<br />
