Abstract
Treatment of FeCl2 with potassium 2-phenyl-3,4-dimethylphospholide pro vides a new C-2-symmetric diphosphaferrocene, -tetramethyl-2,2'-diphen yl-1,1'-diphosphaferrocene (1). Separation by chiral HPLC furnishes bo th antipodes of complex 1, the first diphosphaferrocene to be prepared in enantiopure form. The absolute configuration. of (-)-1 has been de termined by X-ray crystallography.
