| titleOfInvention | Preparation of bidentate ligands |
| abstract | A process is disclosed for preparing bidentate ligands of the formula:n wherein: neach of Ar, R′, R˝ and Y are specifically defined species; nthe x bonds and the y bonds are attached to adjacent carbon atoms on the ring structures; and nn is a whole number in the range of 0-4 where Ar is phenyl: 0-6 where Ar is naphthyl: and 0-8 where Ar is phenanthryl or anthracenyl. n The invention process comprisesn a. reductively coupling an ortho-substituted aromatic moiety to produce a biphenyl compound; b. contacting the biphenyl compound produced in Step (a) with an anion having the structure:n wherein Y, Y′ and R′ are specifically defined species; nunder conditions appropriate to form said bidentate ligand or the dioxide precursor thereof; and c. optionally reducing the intermediate product when the oxy-anion,n is employed as the anion in Step (b). |
