Preparation, characterization and reaction of the first dioxoruthenium(VI) complexes of chiral picket-fence porphyrins

Abstract

Preparation and characterization of dioxoruthenium(VI) picket-fence complexes bearing optically active α-methoxy-α(trifluoromethyl)phenylacetyl residues on both sides of the porphyrin plane (α,β,α,β and α,α,β,β isomers) are described; oxidation of racemic benzyl(methyl)(phenyl)phosphine by the α,β,α,β isomer leads to the formation of optically active phosphine oxide (enantiomeric excess 41%) and proceeds with retention of the configuration of the phosphorus atom.
