Bimetallic Ru-Ir/Rh complexes for catalytic allyl alcohol reduction to propylene.

Bimetallic Ru-Ir/Rh complexes with the Ru-based metalloligand -(bpy)Ru(PPh) (RuP) serve as catalysts for the selective reduction of allyl alcohol to propylene, employing H gas or an electrochemical setup. Metal-metal bonded key π-allyl intermediates [(RuP)M(η-CH)] (M = Ir, Rh) are identified, advancing the understanding of the catalytic processes.

Bis(bipyridine) ruthenium(ii) bis(phosphido) metalloligand: synthesis of heterometallic complexes and application to catalytic (E)-selective alkyne semi-hydrogenation.

The first phosphido derivative of the bis(bipyridine) ruthenium(ii) fragment, cis-[(bpy)2Ru(PPh2)2] ([RuP2]), has been developed and applied as a P-donor metalloligand to form new Ru-Rh, Ru-Ir and Ru2Cu2 heterometallic complexes. The Ru-Ir hydride complex [([RuP2])IrH(NCMe)3][BF4]2 exhibits significant catalytic activity for (E)-selective semi-hydrogenation of alkynes.
