Resolution and Characterization of 2,2'-Bis(Diphenylphosphino)-1,1'-Bibenzimidazole (BIMIP): the First Chiral Atropisomeric Diphosphine Ligand with Hindered Rotation around a N-N Bond

Resolution and Characterization of 2,2'-Bis(Diphenylphosphino)-1,1'-Bibenzimidazole (BIMIP): the First Chiral Atropisomeric Diphosphine Ligand with Hindered Rotation around a N-N Bond

2,2'-Bis(diphenylphosphino)-1,1'-bibenzimidazole BIMIP) was resolved in an enantiomerically pure state through a kinetic resolution process effected by complexation of the racemate with half of the stoichiometric amount of a chiral aminopalladium complex. The enantiopure diphosphine was fu...

Zusammenfassung:2,2'-Bis(diphenylphosphino)-1,1'-bibenzimidazole BIMIP) was resolved in an enantiomerically pure state through a kinetic resolution process effected by complexation of the racemate with half of the stoichiometric amount of a chiral aminopalladium complex. The enantiopure diphosphine was fully characterized by X-ray diffractometric analysis.
