Аннотация: The reaction between enantiopure amino acid amides and metal-coordinated isocyanides such as cis-[Cl₂M(CNR)₂] (M = Pd, Pt) and [ClAu(CNR)] affords chiral acyclic diaminocarbene complexes in 64 to 91% yields with full retention of configuration at stereogenic centers. Structural analysis of the representative Pd^II complexes revealed isostructural enantiomeric pairs with slightly distorted square-planar geometry, featuring labile Pd–Cl bonds trans to the ADC ligand.

Ключевые слова: aminocarbene complexes, palladium complexes, platinum complexes, gold complexes, isocyanide complexes, chiral complexes, amino acid amides.
