The process for preparing a bidentate ligand comprising the steps, (1) contacting with ozone under ozonolysis conditions a suspension in a hydroxylic reaction medium of phenanthrene or a phenanthrene derivative to form an ozonated intermediate, (2) contacting said ozonated intermediate with a reducing agent under conditions appropriate to form the corresponding diol, (3) contacting said diol with a latent displaceable functional group under conditions appropriate to convert the diol to the corresponding difunctional biaryl compound, and (4) contacting said difunctional biaryl compound, with an anion of N, P, As, Sb or Bi under conditions appropriate to form the desired bidentate ligand.
制备双齿配体的过程包括以下步骤:(1)在氧杂环丙烷或氧杂环丙烷衍生物的羟基反应介质悬浮液中,在臭氧裂解条件下与臭氧接触,形成臭氧化中间体,(2)将所述臭氧化中间体在适当条件下与还原剂接触,形成相应的二醇,(3)将所述二醇在适当条件下与潜在可取代官能团接触,将二醇转化为相应的双功能联苯化合物,以及(4)将所述双功能联苯化合物在适当条件下与N、P、As、Sb或Bi的阴离子接触,形成所需的双齿配体。
