Rate-determining t2g-t2g electron transfer: Reaction of (3-formylpentane-2,4-dionato)bis(pentane-2,4-dionato)ruthenium(III) with titanium(III) and formation of (pentane-2,4-dionato)titanium(III)

The rate constants for the reaction of enol and keto forms of pentane-2,4-dione with Ti3+ (at 25°C in 1 M LiCl) are 2.4 × 103 M-1 s-1 and 0.7 M-1 s-1, respectively. (3-Formylpentane-2,4-dionato)bis(pentane-2,4-dionato)ruthenium(III) oxidizes Ti(III) in a reaction that involves two relaxations with rate constants kf′ ? k[Ti(III)]h[H+]-1 + k′ and ks′ ? 20 M-1 s-1, where h = [H+]/([H+] + 0.004 M), k = 2 × 102 M-1 s-1, and k′ = 750 M-1 s-1. These results are interpreted as indicating rate-determining electron transfer within a deprotonated binuclear intermediate.
