Treatment of FeCl2 with potassium 2-phenyl-3,4-dimethylphospholide provides a new C2-symmetric diphosphaferrocene, (±)-3,3′,4,4′-tetramethyl-2,2′-diphenyl-1,1′- diphosphaferrocene (1). Separation by chiral HPLC furnishes both antipodes of complex 1, the first diphosphaferrocene to be prepared in enantiopure form. The absolute configuration of (-)-1 has been determined by X-ray crystallography.
