N-chelate ligands based on chiral oxazolines are efficient co-catalysts in the enantioselective hydrosilylation of acetophenone with a-naphtylphenylsilane. Enantiomeric excess as up to 80% have been achieved. Asymmetric synthesis by means of homogeneous catalysis with transition metal complexes as

Enantiomerically pure C 2 -symmetric diamines and dithioureas as well as a series of monothioureas have been tested as chiral inducers for hydrosilylation of acetophenone with iridium catalysts. Some new N,S-ligands have been synthesized in good yields, one of them bearing four chiral centers. Enant
