Palladium and platinum complexes of L-PhePhos: Acetyl-p-(diphenylphosphino)-L-phenylalanine methyl ester — a chiral ligand for transition metal complexation

Abstract

The crystal structure of the new phenylalanine-based phosphino amino acid L-PhePhos and its reactivity to form the Pd and Pt complexes (L-PhePhos)PdCl2 and (L-PhePhos)PtCl2 is reported. A new platinum hydride was quantitatively formed in the reaction of (L-PhePhos)PtCl2 with NaBH4.Key words: phosphine, amino acid, hydride, platinum, palladium, structure.
