Abstract
2,2'-Bis(diphenylphosphino)-1,1-bibenzimidazole BIMIP) was resolved in an e nantiomerically pure state through a kinetic resolution process effected by complexation of the racemate with half of the stoichiometric amount of a c hiral aminopaliadium complex. The enantiopure diphosphine was fully charact erized by X-ray diffractometric analysis.
