ChemInform Abstract: Synthesis and 31P and 1H NMR Characterization of Two New Chiral Ruthenium Hydrides Containing the trans‐1,2‐Bis((diphenylphosphino)methyl)cyclobutane Ligand (TBPC): cis‐H2Ru(TBPC)2 and trans‐HRuCl(TBPC)2.

Abstract

Dichloro‐cyclooctadieneruthenium and the R isomer of the optically active diphosphine ligand react in refluxing EtOH containing an excess of NEt3 to give the complex (I).
