New Trialkylsilyl Enol Ether Chemistry: Direct 1,2-Bis-azidonation of Triisopropylsilyl Enol Ethers: an Azido-radical Addition Process Promoted by TEMPO
Magnus, Philip,Roe, Michael B.,Hulme, Christopher
, p. 263 - 266 (1995)
Treatment of triisopropylsilyl enol ethers with PhIO/TMSN3/TEMPO(cat.) -45 deg C results in 1,2-bis-azidonation, which appears to occur through a radical addition process; the 1-azido group can be replaced by carbon nucleophiles such as allyl,
Hypervalent iodine chemistry: New oxidation reactions using the iodosylbenzene-trimethylsilyl azide reagent combination. Direct α- and β-azido functionalization of triisopropylsilyl enol ethers

Treatment of triisopropylsilyl (TIPS) enol ethers with PhIO/TMSN3/at -18 to -15°C rapidly (5 min) gave β-azido TIPS enol ethers in high yields, with only traces of the α-azido adduct. The reaction is very sensitive to temperature changes, with
