Chiral ruthenium complexes are disclosed, obtained by reaction of a ruthenium salt with a chiral diphosphonite. Chiral diols with the general structure given in scheme
1
are preferably used as chiral diphosphonites. Said ruthenium complexes can be simply and economically obtained and provide high enantioselectivity on reduction of ketones, β-ketoesters and ketimines.
