High enantioselectivity in the electron transfer reaction between a Ru(II) complex of menbpy anion radical, [Ru(menbpy)(3)](+) [menbpy = 4,4 '-di{(1R,2S,5R)-(-)-menthoxycarbonyl}-2,2 '-bipyridine] and [Co(acac)(3)]: A pulse radiolysis study

摘要

One-electron reduction of [Ru(menbpy)(3)](2+) [menbpy = 4,4'- di{(1R,2S,SR)- (-)- menthoxycarbonyl}-2,2'-bipyridine] by pulse radiolysis produces a Ru(II) complex of a menbpy-centered anion radical, which reduces Delta-[Co(acac)(3)] more rapidly than Lambda-[Co(acac)(3)] with an enantioselectivity of 2.7 in 85% EtOH/H2O.
