Chiral diamines such as (1R,2R)-1,2-diaminocyclohexane or R-2,2′-diamino-1,1′-binaphthalene can be converted into the corresponding diimino(triphenyl)phosphoranes, which serve as C2-symmetric ligands for enantioselective transition metal catalyzed reactions such as copper-mediated cyclopropanations.
手性二胺,如(1R,2R)-1,2-二氨基环己烷或R-2,2′-二氨基-1,1′-联萘,可以转化为相应的二亚氨基(triphenyl)磷烷,这些化合物作为C2对称配体用于催化的选择性过渡金属反应,如铜介导的环丙烯化反应。
