| description | Chiral phosphorus-containing ligands of the formulae: R and R' in (II), which differ from each other, are hydrocarbon (alkyl, cycloalkyl, aryl, aralkyl or alkaryl) radicals; R in (III) is a hydrocarbon (alkyl, cycloalkyl or aryl) radical; R = H or hydrocarbon radical, optionally carrying a CO functional group in (II) and carrying a CO functional group in (III); R and R , necessarily different except when R and R are different, = H, optionally functionalised hydrocarbon radical; R and R = H or optionally functionalised hydrocarbon radical; it being possible for either of R and R to carry an -OPR2 or -NPR'2-NPR2) functional group; it being possible for R and R and the N and C which carry them respectively to form a heterocyclic ring together; or else it being possible for R and R , the N and C which carry them respectively and the intermediate C to form a heterocyclic ring together. Application to an enantioselective reaction (for example, hydrogenation of carbonyl compounds). |
