tertiary amines with trimethylsilyl cyanide was achieved by using a magnetic nanoparticles-supported gold(III)-bipy complex as catalyst to afford the corresponding α-aminonitriles in good to excellent yields in the presence of tert-butyl hydroperoxide under acid-free conditions. The new heterogeneous goldcatalyst can easily be separated from the reaction mixture by using an external magnet and can be recycled

Oxidative α-cyanation of tertiaryamines was achieved by using an MCM-41-immobilised N-alkylethylenediamine ruthenium(III) complex (MCM-41-2N-RuCl3) as catalyst in MeOH at 60 °C in the presence of H2O2 as oxidant and NaCN in acetic acid as a cyanide source to afford the corresponding α-aminonitriles in good yields. The new heterogeneous ruthenium catalyst can easily be prepared by a simple two-step
