Abstract

Hydrogen pool: Recyclable Ir/ZnO-catalysed additive-free transfer hydrogenation of aldehydes and ketones using methanol as hydrogen source was achieved at 110 °C, delivering alcohols in up to 98 % yield. The fine cooperation of ZnO and positively charged IrO_x enables the complete cleavage of O−H and less reactive C−H bonds of methanol to generate active H for carbonyl hydrogenation.
