Oxidative addition of azide anion to triisopropylsilyl enol ethers: Synthesis of α-azido ketones

Article abstract of DOI:10.1016/S0040-4039(00)78855-1

Treatment of triisopropysilyl enol ethers with ceric ammonium nitrate/sodium azide at -20°C in acetonitrile gives α-azido ketones in average to good yields (50-80%).
