    • Treatment of 1 with either AgPF6 or (5)AuCl alone or with a mixture of AgPF6 and 5 or HBF4 and 5 in CH 2C12 led to no detectable formation of either 3 or 4 after 2 h at room temperature. Furthermore, silver was not required for efficient dihydroamination; treatment of 6 with a catalytic amount of, 5)Au(NCAr F, SbF6, NCArF, N≡C-3,5-C6H3(CF3)2, 5 mol , in CH2C12 for 16 h led to quantitive formation of 9 see the Supporting Information
