title: Chloride Substitution Reactions of Cycloruthenated (R)(C)-(+)-N,N-Dimethyl(1-phenylethyl)amine with Pseudohalides: Ruthenium Atom Stereochemistry.
abstract: The diastereoselectivity of chloride substitution by the pseudohalides azide, nitrite, thiocyanate, and cyanate in has been determined by a combination of (1)H and (13)C{(1)H} NMR spectroscopy, UV-visible spectroscopy, circular dichroism, infrared spectroscopy, and single-crystal X-ray crystallography. These chloride substitution reactions proceed with predominant retention of configuration at ruthenium. For the ambidentate ligands thiocyanate and nitrite, the major bonding mode is through their nitrogen donor atoms.
