Chiral Induction via the Disassembly of Diruthenium(II,III) Tetraacetate by Chiral Diphosphines
[Ru-2(mu-O2CCH3)(4)(MeOH)(2)](PF6) reacts with chiral diphosphines (R,R)- and (S,S)-chiraphos, leading to disassembly and production of the enantiomers Lambda-[Ru(eta(2)-O2CCH3)(eta(2)-(R,R)-chiraphos)(2)](PF6) and Delta-[Ru(eta(2)-O2CCH3)(eta(2)-(S,S)-chiraphos)(2)] (PF6) in high yield and purity. X-ray crystallography and solid-state circular dichroism (CD) show that only the indicated isomers are present in the solid state. Solution CD measurements also indicate their predominance in solution.
