Attenuation of intramolecular Ru-H⋯H-N dihydrogen bonding in aminocyclopentadienyl ruthenium hydride complexes containing phosphite ligands

摘要

A discussion about the attenuation of intramolecular Ru-H···H-N dihydrogen bonding in aminocyclopentadienyl ruthenium hydride complexes containing phosphite ligands was presented. Replacement of the dppm ligand in the complex with two less donating triphenyl phosphite ligands reduced the strength of the intramolecular dihydrogen bond. It was found that the triphenyl phosphite complex showed no catalytic activity for reduction of carbon dioxide to formic acid.
