## Abstract Close to perfect enantioselectivity (up to 98% __ee__) is obtained for the formation of amino nitriles using hydrogen cyanide (HCN) as the cyanide source at room temperature for the first time. In an operationally simple process, the catalyst generated from a partially hydrolyzed titani
NH 4 ) 0.926 K 2.074 [H(PO 3 F) 2 ] crystallized from aqueous solution after mixing stoichiometric amounts of (NH 4 ) 2 PO 3 F and K 2 PO 3 F in a 1:1 ratio. The structure contains two sites that are occupied by symmetry-independent cations; one site is occupied by potassium and ammonium in an appro
