Enantioselectivehydrogenationusingchiralcomplexes between atropisomeric diphosphines and ruthenium is a powerful tool for producing chiral compounds. Using a simple and straightforward in situ catalyst preparation, the conditions were optimizedusing molecular hydrogen for both academic and industrialpurposes. This led to the best conditions and the lowest catalytic ratio required for the pressure
