Synthesis and transfer hydrogenation catalysis of chelating triazolylidene ruthenium(II) complexes: Effect of the pendant arm, p-cymene, acetonitrile and butadienesulfonyl co-ligands

Five ruthenium(II) complexes containing two types of chelating triazolylidene and different co-ligands have been successfully synthesised and characterised. The effect of the pendant arm and co-ligands has been investigated by testing their catalytic transfer hydrogenation activity.109
