Clean catalysis with clean solvents – phosphonium tosylates for transfer hydrogenation reactions

Abstract

Molten salts have been applied for the first time as solvents in rhodium‐catalysed transfer hydrogenation reactions. The salts are tetraalkyl/aryl phosphonium tosylates; they are liquid at the reaction temperature and solid at room temperature, thereby facilitating catalyst recovery. In certain cases they can give rise to favourable enantioselectivities.
