OPTICALLY-ACTIVE TRANSITION-METAL COMPLEXES .3. SYNTHESIS OF OPTICALLY-ACTIVE (ETA(4)-AMINODIOLEFIN) TRICARBONYL IRON COMPLEXES - KINETIC RESOLUTION OF A CHIRAL AMINE BY MEANS OF AN OPTICALLY-ACTIVE DIENYL IRON CATION

The synthesis of optically active eta(4)-(aminodiolefin)tricarbonyl ir on complexes by the nucleophilic addition of primary and secondary ami nes to the optically active ricarbonyl-(1R)-(eta(5)-methyl-nopadienyl) iron(1+) cation (4) is described. Under either kinetic or thermodynami c control, the reaction leads to (E,Z)- or (E,E)-diolefin complexes wi th generation of a new chiral carbon centre. Racemic (R/S)-phenylethyl amine was kinetically resolved (de=38%) by treatment with 4 at -78 deg rees C.
