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.
