Platinum complexes modified with a chiral non-racemizing SPO pre-ligand have been applied in the hydration of aromatic nitriles. [Pt(1)3Cl]Cl formed readily from Pt(COD)Cl2. A chiral secondary phosphine oxide complex showed moderate activity in the hydration of para- and meta-substituted benzonitriles, but failed in converting the ortho-substituted derivatives The hydride complex PtH(PR2OH)(PR2O-H···OR2P) (PR2OH = 1) formed from Pt(PPh3)4 and 1, and the cationic complex derived from [Pt(1)3Cl]Cl by a direct chloride abstraction with AgNO3 were proven to be considerably more active, allowing us to extend the scope to the hydration of ortho-substituted aromatic nitriles, including axially chiral [1,1′-binaphthalene]-2,2′-dicarbonitrile. In the hydration of a racemic dinitrile, successful kinetic resolution has been achieved. The catalysts derived from a non-racemizing ligand are the first chiral transition metal-SPO complexes that provide kinetic resolution in the hydration of a racemic chiral nitrile. The synthesis of the target compounds was achieved using (11bR)-4,5-dihydro-3H-Dinaphtho[2,1-c:1′,2′-e]phosphepin 4-oxide as a chiral ligand and dichloro[(1,2,5,6-η)-1,5-cyclooctadiene]platinum or tetrakis(triphenylphosphine)platinum as catalyst. Starting materials included benzonitrile derivatives, naphthalenecarbonitrile, benzeneacetonitrile., [1,1′-binaphthalene]-2,2′-dicarbonitrile.
