Ir‐Catalyzed Transfer Hydrogenation and Alkylation of Aldehydes and Ketones Using Ethanol as the Hydrogen Source

Abstract Bio‐derived ethanol is a promising green and sustainable hydrogen‐donor solvent. Herein, we have developed Ir‐catalyzed transfer hydrogenation of ketones and aldehydes using ethanol as a hydrogen source with amides as simple ligands. Furthermore, the alkylation of ketones and tandem alkylation/transfer hydrogenation of acetophenones is reported with ethanol.
