Mechanisms of Racemization of M(phen)3?+ Ions AIC603 16P
Sir: A few years ago Sutter and Hunt' reported that Cr( ~ h e n ) 3 ~ "(phen = 1,lo-phenanthroline) reacted with ( + ) ~ - C o ( p h e n ) 3 ~to+ yield (-)~-Cr(phen)3~+ and that when (-)~-Co(phen)3~+ was the reactant (+)~-Cr(phen)3~+ resulted. There was thus indicated a substantial (84%) stereospecificity in this outer-sphere redox reaction. The observations demanded additionally that the (rapid) redox reaction must be much slower than the inversion of C r ( ~ h e n ) 3 ~so + , as to allow the optical form of C r ( ~ h e n ) 3 ~which + is oxidized more rapidly by C0(phen)3~+to be continuously regenerated. This required a racemization half-life
