Abstrakt: The stereoselectivities in the electron-transfer reactions of [Co(en)3]2+with eight ? anionic Co(III) complexes in aqueous solution have been determined by observing the enantiomeric excesses of the [Co(en)3]3+product. The results are compared with the ion-pairing stereoselectivity between [Co(en)3]3+and the anionic complexes. Even the ? anionic complexes which form favorable pairs with ?-[Co(en)3]3+yielded the excesses of ?-[Co(en)3]3+product.
