Significance
A hierarchical titanium silicalite-1 (h-TS-1) zeolite-supported Cu catalyst, CuO/h-TS-1, was prepared according to equation 1. CuO/h-TS-1 promoted the oxidative nitrogenation of alkenes with azidotrimethylsilane (2) in MeCN under O2 at 60 °C for 24 hours to give the corresponding oxonitriles 3 (55 examples) in up to 92 % yield (Eq. 2).
Comment
In the reaction of 1-phenylcyclohexene (1d), the catalyst was recovered by filtration and reused six times without a significant loss of its catalytic activity (fresh: 90 %, 7th: 87 %). When the reactions were carried out at 20 °C in the presence of water, β-azido peroxy alcohols (5 examples) were obtained in up to 82 % yield (Eq. 3).
